I use these on occasion when I want to flush my engine out. I ran Mobil 1 20w50 for 3k mi. It came out black. I filled the crank with a 15w40 Diesel oil and a ST3614, and ran it for 100 mi. then dumped it. The oil pressure was fine and I really didn't notice ant difference. I normally run Mobil 1 20w50 and a Harley Black filter. I called Champion labs and the y sent me the attachments.
ngoti8tor: I have been looking at one of the K&P filters pretty seriously myself. Just wondering if you noticed a bump in oil pressure and a decrease in oil temp after you put yours on? Got any numbers you'd care to share? Thanks.
Does anyone have a favorite oil filter? The only one I have used is the chrome HD ( $15.00 a pop) but am wondering if there is another one that is maybe better and less $$'s. I have seen K&N but haven't inquired about them... Just in the habit of getting HD I guess.
I've been using k&N filters on my 08 Ultra and never had an issue. Like the fact its easy to remove with the nut that is welded on the end.
