Great Air Filter

steven June 7, 2026

I have used K%26N for over 30 years. These air filters are the best. Twice a year I wash them out and reoil them and I am good to go. I have never had to replace one in one of my cars or trucks. I end up selling the vehicle before they go bad.

This is worth every penny. I would recommend this for any car. The horsepower increase is quite noticeable as well.

Best Air Filter EVER

mike August 12, 2026

This is by far the very best air filter for your vehicle. Definitely noticed a slight pep in the gas pedal acceleration and a slight growl when accelerating heavy. Very nice.

Super Easy

DJ July 19, 2022

Don't listen to my previous review. Filter fit right in once realizing the pleats don't face the same way as the OEM filter. Grabbed some food and rotated the filter 90 degrees and wham, blam chicken & spam, she fit right in. Don't recommend changing on an empty stomach.

It *FITS* (Forester/Legacy/Outback 2008+)

Ryan May 5, 2026

Yes, the filter is larger than a cheap, paper filter. No, you do not need to *bend* anything. You need to open the filter housing (airbox) appropriately which requires not much more effort (GASP! More WORK! With TOOLS!!!). Several ways to do this. Easiest is loosening the circle clamp downstream of the airbox. This provides enough play in the joint to open the airbox top ~2.5". Also possible to loosen/remove the retention bolt holding the entire airbox assy to the firewall. Don't seek quality parts if you haven't the capacity to use them properly. Don't berate a quality part out of stupidity and/or immaturity. Mind you, one cannot be stupid without being intelligent while one can be immature and quite aged.

I don't like how it was packaged and I didn't like how the boxes sticker was ripped.

Not Exact Fit

DJ July 19, 2022

Filter doesn't drop right in like OEM filter. Edges need to be trimmed or else take your filter box out and install filter. Not simple at all!

Outback or Legacy. DO NOT BUY

Martin March 15, 2026

Filter does not fit properly. Like others have said, the filter is too big and doesn't fit unless it is forced in and this will bend the pleats and leave a gap where unfiltered air can get into engine.

This part does not fit a 2017 Subaru Outback 3.6 r.

John C. October 7, 2025

As stated in the headline, it does not fit. Slightly too big to latch. Air filter is the problem as other air filters fit as described.
