I have been using K&N 2004 oil filters on my 914. I have an external oil cooler with a Mocal sandwich adapter between the oil filter support and the oil filter. I purchased a Mahle OC28 oil filter. When I tried to install the filter, it was tight against the engine bar. The Mocal filter measured 96mm and the K&N measured 93mm. $10 mistake. (IMG:style_emoticons/default/WTF.gif)

That's what I was trying to compare oil filters vs oil pressure. I doubt if any other filter will flow more than a K&N.

QUOTE(Geezer914 @ Jun 10 2025, 05:11 PM)  That's what I was trying to compare oil filters vs oil pressure. I doubt if any other filter will flow more than a K&N. So what’s going on with your pressure? If I recall you originally had some hot pressure problems with a loose fitting T1 pump - maybe years ago? Thought you got a different T1 pump with a better fit that resolved it (mostly?). Getting worse? |
