Champion CH48111-1 oil filter  In 1974, the first Champion-brand spin-on filter was introduced. Today, Champion Aerospace distributes Champion-brand spin-on oil filters and element filters that incorporate a semi-depth filter media. These filters combine the advantages of both surface and depth-type filtration: high filtering efficiency, controlled porosity for uniform flow, water resistance, and the resistance to impulse and flow fatigue. Champion-brand oil filters keep dirt and harmful particles from damaging your engine. Plus, no other filters on the market have Champion’s unique, resin-impregnated, full-pleat design – 8.2 feet of layered protection for your engine.
