Oil filter K&N or AC DELCO

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

Amsoil and Subaru filters. Other vehicles with horrible oil filter locations I use K&N because I can use a socket to pop them off.

I'm trying out that Rotella T6 5W-40 some of y'all talk about. Just snagged it off Amazon.

I also use K&N filters cause they've got a 1" nut welded on top.

DIY 7500mi interval engine oil using 5qt bottle of Mobil1 0w-20 fuel economy oil (takes the whole thing), a K&N HP-1008 filter (why, because it's so easy to wrench off every time), and a new 9956-41-400 aluminum washer.

I’ve been using K&N air and oil filters in mine for ten years. I run nothing else and will always run K&N. I’m happy with mine. Oil filter number HP1008. I would recommend. The one inch nut on top is often very helpful getting the filter out. I also run K&N oil and air filters in every vehicle I’ve ever owned. There is a noticeable difference in throttle response for the air filter, but I’ve never seen a difference good or bad in the oil filters.

No complaints from my 16 STI running Pennzoil Ultra Platinum and K&N filter.

AC Delco oil filters are now all made in China (but they won't confirm nor deny this), so they have a single package for all markets they serve.

i had a k&n on my car, immediately i noticed how much lighter and cheaper feeling it was compared to the previous bosch filter i had, also noticed it had a round gasket opposed to the flat one found on most oil filters, but despite this i ran it anyways, a month goes by and i notice my car is starting to leave puddles of oil everywhere, i put it in the shop and lift it up and sure enough the oil is leaking right from the shitty gasket on the k&n filter, replaced it with a bosch and haven’t had an issue

The K&N for my car was literally half as thick as the oe, and for that reason alone I swapped back. Yes it was the right one. Personally I’d rather just swap the filter than clean and re oil one that is probably doing a worse job

As good as their airfilters are... their oil filters are as shite. They leak and are downright dangerous.
