K&N 33-2452 Air Filter Product Reviews

I've contemplated buying a K&N Filter for years. I finally purchased one and I'm glad that I did There is a definite difference in response when I hit the gas. The power delivery seems smoother as well.

It's great to know that you can go 50k miles without changing an air filter. A water hose and refresher fluid and the filter is good for another 50k miles. The hp differential between my 2015 GS 350 and a 2017 GS 350 has been negated; and then some. The car breathes easier at the higher rpm and/or three digit mph range with an increase in mpg.

Soon as I put the air filter in, I can feel my car breathe easier and more effortlessly. It's the only air filter I run with. Plus, they basically pay for themselves being washable..

Had a K&N air filter in my Audi and it added a touch of response to throttle, and low and behold, it accomplished the same with my Lexus IS 250. You can actually sense the engine breathing a little easier on take off. I am not talking drag racing here, but rather a more pleasant feel to the first fraction of an inch of gas pedal depression. I did notice that the price has creeped up, say 30 over 10 years, but what are you gonna do. For me, it's worthwhile. How many performance enhancements are there that a novice can install w/o voiding the warranty. A nobrainer.

This filter eliminated the throttle lag in 2nd gear and gave my F-sport a much more linear acceleration. I can't say anything about more power, but it feels much better when I drive hard. Definitely a noticeable difference.
