Seems like a good product which is washable and reusable. I have not noticed any changes in my vehicles performance which is fine.

I have K&N filters on all my vehicles I've had over the years. I just got the newest one for my 2016 Honda Civic. Normally, I have just moved my filter from each vehicle when I bought a new one. (I've had my filter in 3 previous civics but 2016 they chose to use a new filter). I have one in my Honda Fit as well as my Ford F-350 and am happy with the performance and fuel mileage.

Got this air filter yesterday, went to install it and when I pulled the factory filter out which only had 2000 miles on it as my car is brand new I saw that it had already let a lot of larger particals pass by into the housing. So after removing the stock filter and cleaning the air box, I unwrapped the new K&N, it fit like a glove. I closed up the air box, started the car and you could tell right away by the sound that it had more air flow sounded much better then stock. l then went for a drive and the car now accelerates quicker, runs smoother and has more passing power and is just a great improvement over stock. Just by replacing a stock part with a much higher quality one! Highly recommended. Don't forget to put the sticker that comes with it on the top of your air box so some dummy changing your oil doesn't throw your filter away and try and sell a stock one to you or your wife, if you let her take it in for a oil change. 5 stars would buy again in a heart beat.

This is the latest filter for the 2017 / 18 Honda Civic Type R. As long as you are aware how to get access into the Air Filter box then its a simple replacement. Slightly louder that the standard filter but not an issue for me. Great filter.

Makes the bypass valve louder than with the stock filter.
