Volant Cold Air Filter: The Definitive Guide to Enhanced Engine Performance and Protection
A Volant cold air filter is a high-performance aftermarket automotive component designed to significantly improve engine efficiency, increase horsepower and torque, reduce maintenance intervals, and provide superior protection against contaminants. By replacing the factory air intake system with a engineered setup that draws in denser, cooler air from outside the engine bay, Volant filters directly address a key limitation of stock vehicles, leading to measurable gains in throttle response, fuel economy, and overall engine longevity. This comprehensive guide details every aspect of Volant cold air intakes, from their fundamental operation and proven benefits to precise installation procedures and long-term care, providing all the practical knowledge needed to make an informed decision for your vehicle.
Understanding the Volant Cold Air Filter System
At its core, a Volant cold air intake system is not merely a filter replacement but a complete redesign of the air delivery path to your engine. The standard factory air box is typically located within the engine compartment, an area that becomes heated by radiator exhaust, engine block radiation, and other components. This results in the engine ingesting warm, less dense air. The Volant system replaces this with a dedicated air inlet duct, often routed to a fender well or grille area, that sources air from outside this heat-soaked environment. This air is cooler and denser, meaning it contains more oxygen molecules per cubic unit. The centerpiece of this system is the Volant filter itself, a high-flow, washable unit housed within a sealed or shielded box. This design ensures that the volume of air reaching the engine is maximized in both quantity and quality, which is the foundational principle for performance improvement.
The Critical Role of Air Density in Engine Combustion
Internal combustion engines operate on the basic principle of mixing fuel with air and igniting it. The power generated is directly proportional to the efficiency and completeness of this combustion event. Cooler air is denser air. Denser air packs more oxygen into the same volume. More oxygen available during combustion allows the engine control unit to precisely meter and burn more fuel, resulting in a more powerful explosion within the cylinder. This translates directly to increased horsepower and torque. Conversely, hot, thin air from the engine bay provides less oxygen, forcing the engine to work harder for the same output, often leading to pre-ignition or knocking under load. The Volant system’s primary function is to guarantee a consistent supply of this dense, cool air, thereby optimizing the combustion process. This is not a minor adjustment; it is a fundamental correction to an inherent design compromise in most production vehicles.
Volant’s Design Philosophy and Construction Quality
Volant Systems has built its reputation on specific engineering principles that differentiate its products from competitors. The fully enclosed air box is a signature feature. Unlike open-element intakes that simply place a filter in the engine bay, Volant’s box seals the filter from underhood heat. This prevents the intake of hot air radiated from the exhaust manifold, radiator, and other components, which can significantly degrade performance gains. The box is constructed from durable, heat-resistant materials like polyethylene or polished stainless steel. Another key aspect is the filter media. Volant uses a proprietary, five-layer synthetic filter media that is both exceptionally high-flow and highly efficient at trapping microscopic dirt and debris. This media is oiled to enhance particle adhesion but is designed to be washable and reusable for the life of the vehicle. The intake tubes are mandrel-bent for smooth, unrestricted airflow and are precisely engineered for each vehicle application to ensure perfect fitment and utilize existing mounting points.
Tangible Performance Benefits and Real-World Results
The installation of a Volant cold air filter system yields a suite of interconnected benefits that drivers can both feel and measure. The most immediate sensation is improved throttle response. With less restriction and cooler, denser air available, the engine reacts more quickly to accelerator input, eliminating the lag often associated with stock paper filters and plastic intake tracts. This translates to a more responsive and engaging driving experience. Regarding power, gains are well-documented. While specific numbers vary by vehicle, engine size, and other modifications, typical increases range from 5 to 20 horsepower and a similar bump in torque. These are not peak-only gains; the improved torque curve is often broader, providing more usable power across the mid-range RPM band where daily driving occurs.
Fuel economy can see a modest improvement, typically between 1 to 3 miles per gallon. This occurs because a more efficient combustion process and reduced engine workload allow the engine to operate more effectively. The engine does not have to strain as hard to produce the same power, so it can use slightly less fuel under light-load conditions such as highway cruising. It is crucial to manage expectations; the primary goal is performance, with fuel economy as a potential secondary benefit. Engine protection is another major advantage. The multi-stage synthetic filter media offers filtration efficiency that meets or exceeds OEM standards, often capturing particles as small as 5 microns. This means less abrasive dirt enters the engine, reducing wear on cylinder walls, piston rings, and bearings over time, thereby contributing to extended engine life. The reusable nature of the filter also eliminates the recurring cost and waste of disposable paper filters.
Step-by-Step Installation Guide for a Typical Volant System
Installing a Volant cold air intake is generally a straightforward process designed for the enthusiast or competent DIYer. Always begin by disconnecting the vehicle’s negative battery cable to prevent any electrical shorts or accidental engine starts. Gather the necessary tools: basic socket and wrench sets, screwdrivers, and possibly a trim removal tool. The process follows a logical sequence of removal and replacement.
First, locate and remove the factory air intake assembly. This usually involves loosening clamps on the intake tube, unclipping the mass airflow sensor connector, releasing any breather hoses, and unbolting the air box from its mounting points. Carefully remove the entire assembly, setting aside the mass airflow sensor if it is to be transferred. Next, prepare the Volant components. Install the provided rubber grommets or isolators into the new air box. Transfer the mass airflow sensor from the old intake tube to the new Volant tube, using the supplied hardware and ensuring a tight, leak-free seal. A leak at this point can cause serious drivability issues.
Then, position the main air intake tube and connect it to the throttle body, tightening the hose clamp securely. Route any crankcase ventilation or breather hoses to their new ports on the Volant tube. Now, place the air box into its designated location, usually near the fender well. Secure it using the provided brackets and hardware, often reusing factory mounting holes. Insert the high-flow filter into the air box and secure it with the attached clamp or fastening system. Connect the final section of intake ducting from the air box to the main tube, ensuring all connections are tight and the system is fully sealed. Double-check every clamp, hose connection, and electrical connector. Reconnect the vehicle’s battery.
The Importance of Post-Installation Verification and Tuning
After installation, a critical step is to start the engine and let it idle for several minutes. Listen for any obvious air leaks, which sound like a hissing or whistling. Visually inspect all connections. For modern fuel-injected vehicles with sophisticated engine management, the computer will need to adapt to the increased airflow. Drive the vehicle gently for the first 20-50 miles, allowing the engine control unit to recalibrate its long-term fuel trim values. During this period, the engine may initially run slightly rich or lean as it learns, but this should stabilize quickly. For vehicles that are particularly sensitive, or for those with other performance modifications, a custom tune from a reputable technician can unlock the full potential of the cold air intake by optimizing ignition timing and fuel maps. However, for most stock vehicles, the factory ECU adaptation is sufficient to realize the benefits safely.
Maintenance, Cleaning, and Re-oiling Procedures
One of the standout economic benefits of a Volant filter is its lifetime serviceability. Proper maintenance is essential for sustained performance and protection. A good practice is to inspect the filter element every 12,000 to 15,000 miles, or more frequently if you drive in extremely dusty or off-road conditions. When the filter appears heavily coated with dirt and debris, it is time for cleaning. Volant and other manufacturers sell specific cleaning and re-oiling kits that are mandatory for proper care.
The cleaning process is methodical. First, gently tap the filter to dislodge loose dirt. Then, spray it thoroughly with the dedicated filter cleaner solution, both from the outside and the inside, working it into the pleats. Allow the cleaner to soak for 10-15 minutes to dissolve the embedded dirt and old oil. Next, rinse the filter with a low-pressure stream of cool water from the inside out. This forces particles out the way they came in. Never use hot water or high-pressure spray, as this can damage the delicate synthetic media. Continue rinsing until the water runs completely clear. Shake off excess water and let the filter air dry completely in a shaded area. This is non-negotiable; installing a damp filter can damage the mass airflow sensor.
Once completely dry, the re-oiling step begins. Apply the provided filter oil evenly and sparingly across the entire outer surface of the filter. The oil should be a light, even red or blue tint. Too little oil compromises filtration; too much oil can migrate and foul the mass airflow sensor. A common technique is to place the filter in a plastic bag after applying oil, massage it gently to distribute the oil evenly through the media, then let it sit for 20 minutes. After this, the filter is ready for reinstallation. This entire cycle can be repeated dozens of times, making the initial investment highly cost-effective over the long term.
Comparing Volant to Other Intake Types and Brands
Understanding the competitive landscape clarifies Volant’s unique value proposition. The primary comparison is against three other categories: the stock paper filter system, open-element cold air intakes, and other enclosed cold air intakes.
The stock system is designed for cost, quiet operation, and adequate filtration. It is almost always restrictive and sources hot underhood air, representing the baseline from which all aftermarket systems improve. Open-element intakes replace the air box with a cone filter mounted directly on the intake tube, leaving it exposed in the engine bay. These can improve sound and airflow but suffer from heat saturation. They often draw in hot air at idle and low speeds, negating the "cold air" benefit and sometimes resulting in power loss compared to a sealed system like Volant’s.
Compared to other enclosed cold air intakes, Volant distinguishes itself with its focus on a true sealed box, high-quality materials, and vehicle-specific engineering. Some competitors may use cheaper materials, less effective sealing methods, or universal fitment kits that require modification. Volant’s precise fitment ensures no check engine lights related to airflow and maintains proper clearance with other engine components. The durability of the polymer boxes and the efficiency of their filter media are consistently highlighted in long-term user reviews.
Addressing Common Concerns and Misconceptions
A frequent question is whether a cold air intake will void the vehicle’s factory warranty. In the United States, under the Magnuson-Moss Warranty Act, the dealer or manufacturer must prove that the aftermarket part directly caused a failure to deny warranty coverage. A properly installed Volant intake that does not cause an issue (like an oil-fouled MAF sensor due to over-oiling) is unlikely to affect warranty on unrelated components like the transmission or suspension. However, it is always prudent to check specific warranty terms and retain all stock parts.
Another concern is the potential for hydrolock, where water is ingested into the engine through a low-mounted intake. Volant designs its systems with this in mind. The air inlet is strategically positioned to minimize this risk, often using factory-style pathways. For vehicles used in severe weather, an optional hydroshield pre-filter sock is available from Volant. This water-resistant cover sheds moisture while allowing air to pass, providing an extra layer of protection against rare but catastrophic water ingestion.
Some users worry about maintenance complexity. While cleaning a reusable filter requires more effort than swapping a paper one, the process is simple, takes less than an hour twice a year for most drivers, and yields significant long-term savings. The myth that high-flow filters offer worse filtration has been debunked by independent testing. Quality synthetic media like Volant’s can offer superior airflow while matching or exceeding the filtration efficiency of dense paper elements, which become more restrictive as they load with dirt.
Vehicle-Specific Applications and Selection Criteria
Volant produces systems for a vast array of vehicles: gasoline and diesel trucks, SUVs, performance cars, and even some imports. The selection process begins with identifying the exact year, make, model, and engine size of your vehicle. For trucks and SUVs used for towing, the increased torque from a cold air intake is particularly beneficial, reducing strain when pulling heavy loads. For performance cars, the focus is on maximizing horsepower gains and improving throttle sharpness.
When choosing, consider the material options. Volant offers systems with polyethylene boxes, which are lightweight and corrosion-proof, and systems with polished stainless steel boxes for a show-quality appearance under the hood. The performance difference is negligible; the choice is primarily aesthetic. Also, decide if you want a system with a traditional dry-style synthetic filter or the oiled version. Both are washable, but the oiled type generally offers marginally better filtration for very fine dust, which is crucial for off-road applications. Ensure the kit includes all necessary hardware, detailed instructions, and is certified for street use in all 50 states, which Volant systems typically are.
Long-Term Ownership Costs and Value Assessment
The initial purchase price of a Volant cold air intake is an investment. When evaluating this cost, consider the long-term economics. First, you eliminate the recurring expense of disposable paper air filters, which for many vehicles cost between twenty and forty dollars each and are replaced every 15,000 to 30,000 miles. Over 100,000 miles, this savings alone can offset a significant portion of the Volant kit’s price. Second, the potential gains in fuel economy, though modest, contribute ongoing operational savings. Third, the contribution to reduced engine wear is an intangible but real value that can postpone major repairs.
The performance and driving experience benefits are immediate and permanent for as long as you own the vehicle. The resale value can also be positively affected, as a well-maintained, quality performance modification like a Volant intake is often seen as a plus by knowledgeable buyers, especially in the truck and sportscar markets. Compared to other performance modifications, a cold air intake is among the most cost-effective per horsepower gained and is completely reversible if needed.
Real-World User Experiences and Case Studies
Anecdotal evidence from countless automotive forums, enthusiast groups, and product reviews consistently supports the technical claims. Truck owners, particularly those with full-size pickups like the Ford F-150, Chevrolet Silverado, or Ram 1500, report noticeable improvements in towing capability, with the engine feeling less strained on inclines and requiring fewer downshifts. SUV drivers note better passing power and a more responsive feel during daily commuting. Sports car enthusiasts appreciate the more aggressive intake sound and the sharper accelerator pedal response, which enhances the driving dynamics.
A common testimonial revolves around the perceived engine "breathing easier." Many users describe a smoother power delivery and a reduction in the feeling of engine strain at higher RPMs. The durability of the kits is also frequently praised, with users reporting trouble-free operation for many years and over hundreds of thousands of miles with only regular filter maintenance. The sealed box design receives specific acclaim for preventing heat soak during summer traffic or slow off-road crawling, conditions where open intakes often fail.
