Champion - a French-American company - delivered parts for the first Ford automobiles and the first jet planes. Well, mostly in the form of Champion spark plugs, but any company that can boast to have a part in over 300 Formula 1 Grand Prix victories makes top-level products.
All of Champion's filters were virtually reinvented in 2011, when they aimed at matching or improving on OE standards. The motto "More Power, More Fun" says it all.
You can easily install an air filter yourself. They are made according to the specifications of the engine manufacturers, so a snug fit is guaranteed. Their main function is to filter out harmful elements from the air intake, which has a direct effect on the life and performance of your engine.
