This filter protects your engine by trapping harmful particles such as metallic chips, dust, dirt, and any other elements caused by abnormal engine wear. The coil spring design and shortened can height make installation simple. Increased wall thickness and center tube improve structural stability and strength, while the increased lid thickness allows higher burst and impulse testing. Includes a zinc-plated stud to protect against rust buildup and corrosion. The eight-hole inlet design gives you 30% more inlet flow area. No other filters have Champion's full-pleat design with resin-impregnated micronic filter media. They trap and hold more dirt and harmful particuls during normal operating time than comparable filters.
