K&N Engineering Airforce Pre-Cleaner Foam Filter Wrap Extend your K&N air filter life with the K&N Engineering Airforce Pre-Cleaner — a purpose-built foam filter wrap that reduces dust intake and lengthens service intervals in harsh, dusty environments. Key Features Improves filtration by capturing large dust and debris before it reaches the primary K&N air filter. Two foam options : Red pre-cleaners are oiled after cleaning for added particle adhesion; Gray pre-cleaners are non-oiled with finer foam cells for applications where oil is not desired. Reusable & washable : Clean with K&N Cleaner or mild soap and water, then re-oil (red) as recommended. Open-cell construction designed for airflow preservation while maximizing contaminant capture. Benefits Longer service intervals for your K&N air filter in extreme conditions Easy maintenance — simple washing and re-oiling process Compatible with a wide range of K&N air filters and off-road vehicles Tip: Follow K&N cleaning and re-oiling instructions for optimal performance and longevity. Choose red for oiled protection or gray for non-oiled applications.
