Eddie Motorsports’ billet aluminum air cleaners are true billet, CNC machined from a single block of high quality aluminum. Don’t be fooled by other companies offering “billet” air cleaners that are really just cheap cast imported pieces. The quality of billet aluminum, manufactured in the USA, is obvious and undeniable. When building a quality ride, don’t skimp on something as noticeable as your air cleaner. Our new Diamond series offers a fresh and innovative look for your engine accessories. We use a cross hatch machining process to give the accessories a raised metal diamond appearance. With the Eddie Motorsports Highlight finish, we diamond cut the parts after they have been Fusion coated.
