K&N Round Air Filter 14in OD / 12in ID / 2.313in Height

About the manufacturer

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. One K&N replacement air filter costs less than replacing disposable air filters over and over again. The E-3740 is simple to install and is custom designed to fit right into the factory air box of older Ford Scorpio and Peugeot models, as well as other applications.
