Owner reviews for air filter

STP premium air filter has been working for me for a while now. I've had no issues with it and it was $20 USD.

I’ve had the K&N washable engine and cabin filters in the car for about 10-15k miles now. No issues so far.

I worked at advanced auto for a bit and got a K&N filter for a discount. Didn't get it for performance but it works fine and they are reusable so saving money in the long term I think.

I've got a K&N filter in my '22 Sport 2.0T. No issues at the dealer, never even brought up.

I actually bought the OEM Toyota denso. Made in Japan. And just the denso branded one made in china that was $10 less. When comparing the two the filter material and number of pleats was exactly the same. Only difference was the finish was better on the Japan version. Things were cut cleaner. But from what I could tell it made no material impact to the filter capabilities.. so that's what I buy off amazon.

Get one from K&N and wash it every 6 months, lasts for many years

The K&N high flow filters actually make a large difference... IF and ONLY IF you upgrade the intake and delete the OEM airbox with it. If you plan to keep the OEM intake and airbox, it will make not much of a difference.

I've run them on basically everything I've owned for the past 15 years. People hate them because they claim the oil fouls the MAF and that they let in more junk. I've never had a MAF fail and I've had two F-150s go over 200,000 miles on them with their original motors. My current F-150 has 239,000 and counting, no problems with it. Why buy them? I do it because they're re-usable. I think the K&N for my current F-150 was $45 when I got it, and the Motorcraft filters are $10-12. So over time it will save money, kind of, if you don't mind the work. Would I do it again? Nah. I'm done with them because it *is* kind of a pain in the butt to clean and oil them all the time. On two vehicles they added a bit of pleasing intake noise but again, eh. No big deal. I wouldn't waste the money. Just get the manufacturer filter and swap it out every year.

I see no benefit in spending more than $12-$16 on OEM supplier air filter (Mann, Heignst or what have you). Marketing can try their best but I just ain't buying it.

Second, these things suck! Buy a Non-Oiled cold air intake instead. If this is a Planted ad, K&N even has one, I have it on my TRDOR. Third, I am a dealer parts guy as my career... And, yes, I Know better. And yet I STILL over oiled my K&N filter and killed an expensive Mass Air Flow sensor on my truck. So I will Never use an oiled filter again. Old technology, imho.
