The PERRIN High Flow Washable Replacement Air Filter is the last filter you will ever need to buy. Not only is it washable, but it will increase horsepower with very little work to install, making it one of the easiest upgrades for your car!
PERRIN Panel Filters use open cell foam to capture dust and dirt. Foam filter elements offer superior performance with minimal airflow restriction and amazing dirt holding capacity. Washable and reusable, PERRIN Foam Filters can last the life of your vehicle.
Cleaning is simple! Just spray on your oil filter cleaner, let it sit on the filter element for a few moments. Then simply rinse away the cleaner and dirt. Once your filter is dry, spray on a fresh coat of oil, and you are ready to go.
To clean, use the Uni Foam Filter Cleaner Kit, part number UFM-400, available on Amazon!
Installation can be performed by anyone! The air filter is designed to be replaced without tools and as part of the yearly maintenance, making this one of the easiest upgrades for your car.
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle. Questions? Contact [email protected].
