Great product for a little better breathing of your vehicle. Best to use when changing out the exhaust system for optimum air flow through the system.

For anybody that wants to up there RPM & save on gas K&N is a must have. With in moments of installation you feel the power behind the stearing wheel it's just amazing the diffrence it makes ill never switch back. It's K&N for life..

I have used these air filters for years on several different vehicles. They improve performance and save gas. Worth the extra cost.

I have had a K&N air filter in my 1998 Saturn SC2 for 15 years and 235,000 miles. I have gotten more than my moneys worth out of the filter. I also installed K&N filters on my 2006 Silverado and my wife's 2007 CTS.

Easy to replace, took literally 10 minutes. For a lifetime filter, the price was excellent. My car can breathe again!! Great product. Also use only K&N air filters on my Harley. Excellent choice, don't hesitate if you're thinking about purchasing one. Buy it!!

People who say they can't tell a difference, don't pay attention to how their vehicle operates in ALL conditions! Anyway,all I can say is im VERY pleased with it! The biggest difference for my vehicle is greatly improved throttle response (which is what I was looking for) and a little added torque. I can really tell a difference on power robbing hills also! I've known about K&N filters since the 70's80's and cannot believe I haven't used on until now! What a dummy! K&N for life! My vehicle is a 2003 CADILLAC Cts,base model. I may have to get the cold air intake next!

This is the 4th K&N Air Filter I own. They are the way to go ONLY if you learn to clean them and paint them with new oil properly.Do not buy one in if you are not going to clean them on a scheduled maintenance. They still look clean after 3 or 4 months but if you soak them down with the cleaner and pressure wash (Vegtable Spray) in your utility sink with hot water you will not believe how dirty they get. I even have one on my Tecumseh 6Hp Lawn Mower Engine. Yes they make a custom filter for that also. Craig
