Designed with a proprietary SuperNano-Web media, this filter combines a high-flow base media with a Nano membrane layer to maximize airflow while effectively filtering out dirt and debris. Its advanced design ensures your engine receives a steady supply of clean air, which can translate into increased horsepower and torque. This filter is suitable for many Injen intake systems as well as universal applications, providing a direct fit with a tight, no-leak seal thanks to integrated flange ridges.

The deep pleats within the media enhance airflow capacity and filtration efficiency, ensuring your engine remains protected under demanding conditions. It is fully serviceable and can be cleaned with a simple blast of compressed air, requiring no oil to maintain optimal performance. As a dry filter, it eliminates concerns about oil fouling your Mass Air Flow (MAF) sensor, thereby maintaining sensor accuracy and longevity.
Manufactured in Pomona, California, this filter is designed to withstand rigorous testing, including lab evaluations and real-world racing conditions such as the Baja 1000 and Middle Eastern sand dunes. It features a 4-inch flange inside diameter, a 5.5-inch base outside diameter, and a media height of 5.4 inches, with overall dimensions tailored to fit a variety of performance applications. The closed top design and conical shape optimize airflow and filtration, making it an ideal choice for enthusiasts seeking enhanced engine performance and protection.
