Oil filter K&N or Castrol

Been running this on my 03’ hatch and it’s been great.

The oil, no, K&N filters I've been using for almost a decade. Doesn't seem to have any issues. And I like the 1 inch nut on it.

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

OEM. I order a bunch off of Rock Auto. Two of the K&Ns I've had leaked just the tiniest bit but enough to be annoying. Granted, I'm not on a stock turbo or stock by any means, so maybe that has something to do with it.

It\u2019s crap. Most filters are 20 microns; K&N have one that\u2019s 10. Put your money into getting a better oil filter instead of buying into the snake oil.

I run the mobil 1 filter but oem is a good option. I used to use K&N but had the issue of not one but two of them leaking around the gasket.
