K&N 33-2137 Air Filter Product Reviews

The performance increase provided by K&N air filters is obvious but, they also make my Lexus LS sound great.

Awesome product. Delivered on time and properly packaged. Fits like a glove in my Lexus I immediately felt 3+hp and is quiet when cruising. I highly recommend, to give your car the lungs to breathe.

So far so good. But just have had in for a couple of weeks. Again, so far I like what I have seen.
