I take the car to the dealer for my oil service as I know they will let me know about any wear and tear. They brought out the air filter which was filthy. I thanked them for the info and politely declined the offer to replace with another paper filter that will only last a year (Car is a 2014) I immediately went home and ordered the K&N and couldn't be happier. I didn't even know they also made cabin air filters....that is next on the list. Gotta love lifetime maintenance items!!!

Filter came on time and in good shape. I've always wanted to try K & N's and they didn't let me down. They woke up the sound of my ride a little bit and I'm sure they will do the job keeping my engine air clean. Good Deal!

At first I was skeptical as to the performance, but California has very strict emissions standards. The CARB regulations ruled out using a cold air intake on my Mustang, so this was a legal option. I was very surprised at the quality and ease of installation. (And you cant beat a one million mile filter rating)

K&N has been around for what seems like forever, and that's because they make a great product. I've had these filters on every Mustang I've owned, and see no reason to buy anything else. I'll be purchasing another for my wife's Hyundai Sonata turbo also. Great product, great site, fast shipping. Can't beat it.
