Oil filter K&N or AMSOIL

I run K&N filters and mobil-1 5W-30 at 350k km

I use the K&N 170 on my 1999 883C, have for years. Not sure why Amazon is saying "not for your model", I've literally been using it for the last 16 years and 70,000 miles, and have ordered 6 of them from Amazon over that time period.

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.

I was skeptical, but I started using it and their best filter in my '98 Durango 5.9 (gas). I ran it for the full 25 K(+) and sent an oil sample out to a 3rd party "Analysts, Inc." for a full analysis - including spectrographic. Basically, their recommendation was that the oil showed minimal contamination, acceptable viscosity, and was still OK for continued use and to re-sample at next interval.

I use amsoil, pricy but the filter is what's really worth it and before I changed my valve seals I burnt quite a bit less, it went from a quart every 800-1k miles to a quarter quart in that same time frame.

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.

Engine carbon cause the dirty looking oil no filter can get rid of the carbon color and I don't wait 5000 miles I change every month but put on 500 km every week highway also your oils detergents could have cleaned some crap from engine I would do a change sooner myself am switching to Pennzoil ultra platinum 5w 30 and k&n gold for maximum flow rate/ oil pressure and 30 micron rating (70 micron is human hair) year round I've got about 335,000 km on Buick Lucerne 3800 series and aiming for 500,000 I used wix XP for years bought bulk from rockauto and got carbon black every change including my ram1500 only 150,000 km highway

I have pulled multiple K&n filters out that have looked a little bent like this. The smashed K&n is definitely shorter.

Just had an amsoil filter fail at the gasket. The inner diameter was too small causing a crease in the gasket that leaked after 4 months use. Nearly ran me dry.
