Oil filter K&N or Hengst

If opting for third-party filters, choose high-quality brands like WIX, Purolator, or K&N, which offer reliable alternatives that match Subaru’s specifications.

i use k&n wrench off filters because they use solid oem designs, but add a useful hex head i can use for when i was an idiot before and cranked it on there calling it hand tight XD

Picked up a K&N clean it every 5-6 months with my Pennzoil Platinum oil change. I got the filter with Ford loyalty points when I bought the car. Always use K&N.

I wanted to get a Wix filter last time, but they were out. I ended up getting a k&n and it's pretty good.

For oil i used : Motul 7100 10W-40 (4L but only 3L required.)

K&N KN-303 Filter

Ive never had a single issue using either mobil 1 or valvoline in any of the cars I've owned. K&N filters typically.

It’s easy peasy to DIY at every OCI (5k mi or 6 mos whichever comes first, 2014 Mazda6 Touring 6MT). Been doing it, for decades (various makes; at times with an oil boy vacuum fluid extractor). Will be changing mine tomorrow. This time, will try Kirkland 0W20, with a German Hengst oil filter (identical dimensions/specs Made in Japan OEM Mazda PE01-14-302) plus Lubro Moly MoS2 (molybdenum).

I use Rotella T6 5w40 with K&N HP oil filter on my 03 DE daily/drift car.

Oil is oil, however those K&N filters are trash, definitely wouldn’t put that in my car.

I've just experienced this same problem with my 2017 Buick. I have the UFI cap and the dealers used the Hengst filter 7 of the 9 times I had it changed at the dealer. Using a Hengst filter in the UFI cap results in the oil bypassing the oil filter all the time. The UFI cap expects the bypass valve to be on the filter and the Hengst filter just has an open hole there resulting in the car being run for about 50,000 of its 70,000 mile life WITHOUT an oil filter.
