8-Layer Oiled Cotton Gauze Air Filter by Injen

With a rich history in racing and street performance, Injen Technology has proven itself as a leader in filtration engineering and technology. Lab-tested and race-proven, Injen’s air filter line features state-of-the-art designs and performance. All of Injen’s 8-layer cotton gauze oiled air filters feature a tightly layered media that is specified for our use, along with a proprietary filter oil that includes highly advanced tackifiers to stop as much dirt and contaminants as possible. This allows our 8-layer oiled cotton gauze air filters to flow the maximum amount of air, all while protecting your valuable engine from harmful dirt and debris. Injen SuperNano-Web air filters are completely cleanable with the use of our Pro Tech air filter cleaning kit, part number X-1030. Order yours today!

Our media was lab tested by an outside company to ensure accuracy and filtration performance. We then took that data and tested in the harshest conditions racing the Baja 1000 in Mexico and also throughout the dunes of the Middle East, all to provide you with the best air filter that money can buy.

Injen’s 8-layer oiled cotton gauze media was designed to improve airflow and filtration efficiency resulting in increased horsepower and torque, all while protecting your engine from harmful dirt and contaminants.
