This product is superb / excellent. My 2016 Acura RDX AWD became more responsive and added few more horsepower. My engine can breathe more freely. And you can really feel the difference. I highly recommend K&N Air Intake Filters to everyone. Try it and you will never ever say goodbye..

I've used these filters for 30 years. Love the extra and quicker engine response they provide my vehicles. Even my old Prius drove better.

Great air filter, I had one on my truck & wanted to replace the stock air filter on my wife’s car. I wish I knew that the “STOP” sticker was included with the filter. I wouldn’t have ordered the sticker separately.
