"I recently purchased 2 K & N air filters. There was a noticeable difference in the way my engine sounded. I definately feel a performance gain." —Scott M from Savanna, IL bought a K&N Air Filters for a 2006 Cadillac CTS.
"Filter comes pre-oiled and ready to install. It fit perfectly in the stock airbox. The rubber seal material is dense,yet supple. I like K&N filters and have put them in most of my vehicles. They flow well when they're dirty, but they can easily be cleaned and re-oiled. K&N sells a nice kit for that, too." —Martin D from Crest Hill, IL bought a K&N Air Filters for a 2006 Cadillac CTS, 3.5L V6.
