Great air filter! Nothing better on the market. I know I am making this up but as soon as I put your filter in my Acura ILX it ran smoother and faster. It likes it!!!!!!

I've been using K&N filter for 20 years. I got this one for my new Acura MDX. Seems to work great, no complaints.

I have a 2004 Acura TSX... and this was a BREEZE to install. The directions were extremely easy to follow and it took just under an hour to get on, and it sounds amazing. I can actually hear my Vtec kicking in!
