WIX Racing Filters Air Filters

WIX Racing Filters Air Filters: Built for the Demands of Competition

When a race engine's survival depends on clean, unrestricted airflow, few names carry as much weight as WIX Racing Filters. With over 85 years of filtration expertise and a motorsports legacy stretching from grassroots dirt tracks to the NASCAR Cup Series, WIX Racing has engineered its air filters specifically for the punishment that competition demands—high RPMs, intense heat, vibration, and relentless exposure to dust and debris.

Two Distinct Racing Air Filter Lines

WIX Racing offers two purpose-built air filter lines, each targeting a different performance priority. The T-66 series is designed for maximum airflow and horsepower, using the lowest-restriction pure racing media available—ideal for short-burst, all-out performance applications. For longer events where engine protection and endurance matter as much as peak power, the T-88 series utilizes high-efficiency endurance media that balances superior filtration with strong airflow. This dual-line approach means racers at every level—from drag strips to circle tracks—can choose a filter tuned to their specific event and engine needs.

What Sets WIX Racing Air Filters Apart

WIX's unique filter media is engineered to maximize air flow while minimizing restriction, directly contributing to horsepower gains. These filters are developed in close collaboration with engine builders and racing professionals, ensuring real-world performance validation beyond the laboratory. WIX Racing air filters have been track-tested and proven across all levels of stock car, dirt track, off-road, and drag racing—giving competitors confidence in the technology from the moment they fire up the engine.

That credibility reaches the highest levels of motorsport. WIX filters are the only ones officially licensed by NASCAR, and a remarkable 99% of cars in the NASCAR Cup Series compete with WIX products under the hood. WIX also serves as the preferred filter of the World of Outlaws NOS Energy Drink Sprint Car Series, where 900 HP machines require filtration that never compromises. This breadth of real-world validation—from quarter-mile blasts to hundreds-of-laps endurance—is built directly into every WIX Racing air filter element.

Proven Across Every Racing Discipline

Whether the application is a purpose-built circle track car, a tire-shredding drag machine, or a punishing off-road vehicle, WIX Racing air filters are engineered to deliver consistent, trouble-free performance from the green flag to the checkered. The filters are not intended for street use—they are pure racing components, purpose-engineered for the extremes of competition.
