K&N 33-2499 Air Filter Product Reviews

Friday, April 14, 2017 - Part 33-2499
Been using K&N filters in my cars for years. When I get a new car one the first things I do is put in a new K&N filter. I noticed a difference in performance (acceleration) and much smoother start from idle.

I have always had K&N air filters in all my cars. I just acquired a new 2017 Honda Accord and once again, am sold on the product and its results.

I ordered the replacement air filter for my 2013 Honda Accord, it's only been a few weeks. I can't give a good assessment of its performance or gas saving qualities at this point. So far I haven't noticed any fuel savings or increase in thrust horsepower. I do like the quality of manufacturing of the filter. It appears to be well made. I also like the that it's washable and reusable.

I have always used K&N and had great service out of them. My Honda's mileage went from 33 to 35 on the highway with the air off, also the throttle is more responsive. This is on the 3.5 six. It will roar a little louder when you open it up. I'm happy.

No matter what car I have used a K&N filter in, they always get better mileage.
