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.

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.

 Great product and arrived in perfect condition.
Dennis, Tampa, Florida
 Your customer service department provided great service when I had to reorder/exchage air filters. I do like how your air filter works.
Michael Slater, Bondurant, Iowa
 Needed a shorter filter to fit my 383 in a 78 Corvette so I asked a K&N tech if they had something. He sent me an email with this part number (E-3740). Fits perfect and since it is a lifetime filter, you can't beat the price.
