 I am a firm believer in the benefits of this air filter. I drive a 2009 Cadillac CTS 3.6L DI and prior to the installation I would get just under 20 MPG as a slightly aggressive driver. Without changing my driving habits at all and simply replacing with the K&N filter I am currently just above 21 MPG. This product has tangible benefits and I will continue to recommend this product to everybody who doesn't have one. Easy installation and great customer service as they helped me find the correct location for the filter.

 This is the fourth vehicle I had added a K&N Air-filter to. In each instance I have experienced a significant improvement in both mileage and performance. The fact the filter is also re-usable is also a great benefit. Even if I get my vehicle serviced at the dealership, I have a hangtag on the filter-box telling the service tech not to service (or touch) the filter unit. I take care of that myself, using the K&N Filter Service Kit. Thanks for an excellent product and for your consideration of the environment!

 Just what I wanted. Correct fit.

 I purchased a cold air intake kit from Lingenfelter for our 2014 Cadillac CTS-V Sport Wagon. Lingenfelter reccomended this filter over the OEM filter for more air flow.

 Great quality air filter and easy to install.

 Great product! I own a 2010 Cadillac CTS4 V6 3.0L and a simple installation of this K&N air filter lowered my fuel consumption and raised my fuel average by 2 MPG! Really happy!

 I've used K&N air filters on every car or truck I've had in the last 20+ years. I wouldn't use anything else.
