These high quality alloy magnetic sump plugs are specifically for Subaru vehicles. Why do you need a magnetic oil sump plug? The answer to this is simple: As your engine wears small metal particles are left to circulate in your engine oil. These metal particals can and do accellerate wear on your engine. After your first oil change with one of our magnetic sump plugs you will see just how much metalic sludge collects on the magnet! For the sake of a few dollars these are a well worth while precaution! Fitting: Subaru only
