Filter was ordered for a 2013 SRX Cadillac. I ordered the filter online through the K&N website. Ordering was easy. Delivery was quick. The filter fit my vehicle perfectly.

Easy to install. You can Youtube a video of it. I found it wasn't necessary to disconnect the 2 electrical connections. It fits perfectly. I have a long 3000 mi journey ahead of me so increased gas mileage and power would help.

Well built unit and perfect fit. Not much you can do to a SRX but add one of these.

I am a car guy and have been a big fan of K&N products for more than 20 years. Needless to say, all my existing and past cars are/were equipped with K&N filters. Since I am a car guy and not only improve/fix my own vehicles, I also try to help my friends with their cars as well. This particular filter was for one of my friends' 2010 Cadillac SRX. He is not interested what's under the hood, however, the filter managed to wow even him, with the change in performance.

Excellent product that fit. This will save me money many times over, with better fuel economy and not having to change the original filter on a regular basis.
