On cold starts when the oil is really thick and not flowing well some will bypass the filter so the engine has lubrication. IIRC what Fram did was cross list a Honda oil filter with a bypass of 11-16 PSI for a Hyundai application with a bypass of 7-11 PSI because the filter happened to match all the other dimensions and was marginally within spec for bypass PSI. Lo and behold, it bit Fram on the ass when Hyundai Elantras started dying because of insufficient oil pressure. They did not have a filter for Hyundai engines for several years while they figured out what to do.

It looks like they still are having problems with Hyundai engines.

jesse, check the filters. If they look the same, chances are they are the same.
