"I just bought a 2008 Cadillac CTS, it is a pain to find just a standard air filter for this because it is an odd sized/shaped air filter. I got tire of being told we could order it, and for what to wait next time it needed replaced. I ordered the K&N OEM fit air filter, and it was easy to install and now I never have to worry about looking for a replacement filter again. Thanks to K&N! I highly recommend this product to thse of us who have trouble finding filters in stock." —Byron G from Greenville, NC bought a K&N Air Filters for a 2008 Cadillac CTS, 3.6L V6.
"Replacement for the cotton filter look better and gives a little more umph to t he power curve." —Kent A from Mesa, AZ bought a K&N Air Filters for a 2008 Cadillac CTS, 3.6L V6.
"I always install a K&N filter on my cars because of their lifetime warranty and efficacy in protecting my engines.
Engine compartments are getting tighter and my Cadillac CTS is no exeption but with a little patience I was able to install the most recently purchased K&N filter in it. There is a noticeable improvement in acceleration and a slight improvement in MPG. According to my on-board computer I gain almost 1 MPG. It probably would have been more but the joy of unleashing that acceleration no doubt cuts into the MPG gains ;>)" —Rafael V G from Clarksville, TN bought a K&N Air Filters for a 2008 Cadillac CTS, 3.6L V6.
