 This filter works great in my 2012 Cadillac CTS-V! I do notice a slight performance improvement in power and gas mileage. I never have to worry about replacing this filter ever again. This should last a lifetime. This makes my 6th K&N filter purchase. Ever since I found out about K&N, I have never went back to paper filters. K&N makes a filter for all of my cars.

 Have used you product before this and always had outstanding results. Increased air equals increased HP and I believe my Cadillac CTS V breathes better now and so far the results have been great.

 I'm driving a 2014 Cadillac CTS-V. This car is a supercharged 6.2 liter, so it's basically a huge air pump. All the performance sites recommend the K&N high-flow air filter, so I thought I'd give it a try. Aftermarket performance companies are notorious for over-marketing, so I set my expectations low. Big mistake! I didn't expect this much improvement over the stock paper filter, but I can feel the punch of the K&N filter thoughout the rpm range. Previously the CTS-V would accelerate to 120 mph with a half-hearted gas pedal on a stretch of highway I travel regularly. After the K&N that same procedure yields 150 mph! At high rpms the filter really shows it's stuff, but the engine clearly breathes better even at low rpm. Nice work K&N! It's great to find a performance product that lives up to its claims.
