12oz Filter Cleaner

K AND N ENGINEERING 12oz Filter Cleaner is purpose-built for maintaining reusable high-flow air filters found in performance intake systems and stock applications alike. Whether you're a serious automotive enthusiast running a modified engine or a mechanic managing a fleet of vehicles, this specialized cleaner extends filter life, restores airflow efficiency, and prevents costly replacement cycles. The 12 oz pump bottle format delivers controlled application without waste, making it the go-to choice for shops and DIY builders who understand that filter maintenance directly impacts engine performance and fuel economy.

This filter cleaner formula is engineered to dissolve accumulated oil, dirt, and debris trapped in filter media without damaging the delicate mesh or synthetic material structure. K AND N's proven chemistry safely removes buildup that restricts air passage, restoring the filter to near-original airflow characteristics and filtration efficiency. The pump dispenser ensures precise dosing and even coverage across the entire filter surface, preventing oversaturation or missed spots that would compromise cleaning results. Users apply the solution directly to the filter element, allow brief dwell time for the formula to break down contaminants, and rinse thoroughly—a simple process that adds years to filter usability and maintains peak engine breathing.

Mechanics, tuners, and performance-minded drivers benefit most from keeping 12oz Filter Cleaner on hand as part of routine maintenance, especially after dusty driving conditions or high-mileage service intervals. Compatible with K AND N air filters and most cotton-gauze or synthetic reusable filters on the market, this cleaner works equally well on stock intake systems and turbocharged, supercharged, or naturally aspirated builds. Regular cleaning maintains the filtration seal and air velocity needed for dyno-proven horsepower gains, making this small-format bottle an economical investment in engine longevity and consistent performance.
