Overview
Overview
The K&N E-3740 replacement air filter is designed to increase horsepower and acceleration by reducing restriction and increasing air flow to your engine. The E-3740 is made with oiled layers of woven cotton that offer superior filtration and can be washed and reused repeatedly. K&N replacement air filters can go up to 50,000 miles before cleaning is required, depending on driving conditions.
