The PERRIN High-Flow Replacement Air Filter is a reusable, panel-style filter that fits directly into your airbox. It boosts horsepower for a durable, cost-effective performance upgrade.
PERRIN Panel Filters use open cell foam to capture dust and dirt. Washable and reusable, PERRIN Foam Filters can last the life of your vehicle.
Installation can be performed by anyone! The air filter is designed to be replaced without tools and can be cleaned as part of your 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.
Keeping your air filter clean is essential for optimal performance and longevity of your vehicle's engine.
PERRIN Foam Filters arrive pre-oiled with specially formulated filter oil, ready to install straight out of the box. The oil suspends throughout the open-cell foam structure, ensuring dirt particles are captured before they can reach your engine.
