Review part 33-2411

Service and shipping direct from K&N was good. The K&N filter for my new Cadillac CTS V6 works great I've noticed a slight improvement in gas mileage and throttle response acceleration.

Hi K&N, I don't care what people say about all air filters being the same. It is a load of rubbish. However, If I did not see it with my own eyes, I would not have believed it. Since I have installed it on my VE 2011 Holden Berlina 3.0 Liter SIDI Engine, my throttle and acceleration has improved dramatically and have gained more power. Thanks K&N and keep up the good work.

A K&N filter/intake is ALWAYS a good move. Installed on a 2013 Cadillac CTS. A simple, side-by-side comparison of the OEM equipment and the K&N filter will reveal the quality advantage.

Perfect fit, well engineered! Easy to install. Works well. I have a K&N in each of my cars.

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!
