Also the oil filter housing surface is suppose to be flat, no recess, only the filter has a recess for the O Ring. What they mean is when you remove your old filter the O ring from the old filter gets left behind on the oil filter housing therefore placing two O ring filters (usually only happens on model of vehicles when you can see the housing).
