This is genius
If you're Mr maintenance like me this is a godsend. I'm a manager at a major parts store that can verify a wix xp filter is by far he superior full synthetic filter via the synthetic media used is construction. Plus it's close to DOUBLE the size of the OEM black Subaru filter see picture so that means more oil better flow better filtration no leaks plug and play adapter the filters aren't expensive and can be purchased at any O'Reilly's auto parts store so no worries about finding the right filter. The bypass specs check in fine and overall is just doing a better job for ur engine. Pair it with motuls new 8100 power line built specifically for tuned high performance engines with perfect compatibility to those like myself who run ethanol blends. It's the perfect balance between daily and race oil. iIR will have it in stock soon in all weights I was told but perfect to pair with a superior filter that gives u confidence ur cars got 100k in it easy. I've opened mine up for about 500 miles of very spirited driving on occasion to test the oil and filter setup and have had no issues from he adapter. Plan on doing a Blackstone oil test on this cycle to see if motuls out done themselves or if even though everything seems right who knows since it's new. So stay tuned for an update but so far 5 stars easy and free fast shipping!
