The only filter you will ever need to purchase is the PERRIN High-Flow Washable Replacement Air Filter. It's one of the simplest improvements for your car because it's not only washable but also installs quickly and increases horsepower! 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, and 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. Installation is very simple and 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.
