2009 Cadillac DTS air filter

Reviewed By Paul R (West Chicago, IL) Reviewed for a 2009 Cadillac DTS —3/21/2012 8:40 PM

Just purchased a 2009 Cadillac DTS used with 22,000 miles. The K&N air filter was the first change I made to the car. I have K&N filters in four other vehicles and know the benefits of using them. The stock original filter was pluged with dirt so I noticed better perfomance right away. I always make sure to put the K&N sticker under the hood,it keeps the oil change joints from trying to up sell their air filters. Paul, West Chicago Il.

Seem decent.

I can't really tell any difference other than it sounds a little beefy when I step on it.
