Oil filter K&N or OEM Subaru

This is the one to use my guy. On my fxt the cartridge is slightly taller than subarus. So more filter material and its easier to take off because its longer.

Personally I like K&N filters, they come with a nut welded to them so you can use a normal wrench instead of a filter wrench. Gotta be careful not to over tighten them though

Yes, it's absolutely worth it! in fact, I own one myself. I bought mine for $6,500 AUD with around 280,000 km on the odometer, and it's now at over 306,000 km and still going strong.

I have a kn 1 on my truck and winter is about every 1k miles I empty it. Its the 6oz canister and usually about half full. From may till like October I dont even have to look in it because it doesnt get more than an oz of oil build up in it. But man winter time with the condensation sucks.

Use quality oil and filters, changing them often. To this end, oil pickup and baffle are sound upgrades.

I changed the oil/filter at 590 miles on my 25 Forester wilderness.

K&N is good but sacrifices filtration for flow for better performance.

Not sure about mobil1 filters, but stay away from K&N oil filters. I've just used one for an oil flush after extensive maintenance work, and after just 100 km it had collapsed.

Avoid the blue Subaru filters. They are Fram made with cheap components.

K&N filters are some of the worst quality filters on the market.
