Oil filter K&N or Wix

I saw 10 psi more oil pressure across the board from switching to a WIX XP filter. Did this now on all my cars and have the same results. Pretty phenomenal. I used to idle at 20psi like you and now I idle at 30.

What kind of oil filter are you running? My LQ4 was always 40 at idle when warm, about 50 to 60 cruising. I started using AC Delco filters and ended up just under 40 at cruise and 20 hot at idle like you have. Went to a Wix at my next oil change and got the original pressure back. The Delco filter was restricting pressure. No problems since with Wix

What kind of oil filters are you using? Ac delco filters caused similar oil pressure on mine, switched to wix and now it always has like 45psi at hot idle, and around 60 at cold start.

Also the K&N oil filter is superior to HD’s despite the recent upgrade. The K&N has a better flow.

K&N HP1002 because it has a hex on the end that makes taking it off through the wheel well really easy. Don't even have to jack up the car, just remove the rear splash guard.

That is why I always buy a k&n filter where can just use a wrench.

I put a K&N nut topped filter on it and never had to do that again!

Had a conversation with a WIX rep and was told their best filter is done filtering around the 5000 mile range.

K&N oil filters on the other hand, are like the thread count myth for bedsheets. You are paying a shitton more for 480 Egyptian cotton you'll throw out in 3000 mi.

I have pulled multiple K&n filters out that have looked a little bent like this. The smashed K&n is definitely shorter.
