The Injen 8-layer oiled cotton gauze high-performance air filter with a 4.50-inch flange is pre-oiled and designed to boost airflow while trapping contaminants. Deep pleats and layered media maximize flow and filtration; the filter is fully serviceable and should be cleaned with Injen’s Pro Tech kit. Integrated flange ridges ensure a secure seal and a stainless clamp with inner liner prevents leaks, for reliable direct-fit or universal use.
