Product Reviews      Review part 33-2440

 Super easy to install, perfect fit, and quality second to none. I've been using K&N filters in all my vehicles for several years and they are everything as promised. I will continue to replace my stock filters with K&N products in the future as well. Best product you can buy for the money.

 Installed the 2 filters on my 2010 Infiniti M35.  Has great acceleration off the line. The car feels so much smoother and lighter.
