K&N 33-2403 Air Filter Product Reviews

I have used your air filters in the past and found them to perform very well. I put this filter in my 2012 Honda Accord and it seems to have improved the performance. I am considering purchasing your air filter system but, I am a little worried about the installation.

Seems to be working well but dislike the reduction of gas mileage.
