K&N quality
I needed a new filter for the CTS and I've owned K&N before, so thought let's go for it again. Fit was perfect and I like the fact that I can clean and re-oil it rather than replacing them every year....yea I know, I might be overdoing it, but that's me. Yes, I would buy another K&N filter,

Durable, and they work.
I’ve had versions of this filter for all the cars I’ve had for more than 25 years, and I can say these things are bulletproof. Keep them cleaned and serviced and they will last longer than your car.

Great deal and worth the money
Needed new filter so got this one. Like that I can wash, rinse and reinstall. Should save me some money in the future. Easy to install, mostly based on filter location. I haven't seen the so called boost as of yet but will give it some time. Great value especially since it's reusable.

I have this in my car now for a little ...
I have this in my car now for a little over a month. Definitely can hear the difference with a higher air flow and there is a slight increase in pedal response when putting the gas on. Overall I believe it is a worthwhile product.

Perfect fit
The media could not be loaded. I ordered the wrong size originally and got a full refund and replaced my part within just a few days. It was such a perfect fit I was very satisfied once I finished… might be getting a cold air intake from them in the future
