K&N E-1998 Air Filter Product Reviews

Great product. Fit is a little snug in the air box but slips in with a little coaxing. Noticed a wonderful gain in acceleration from a stop and haven't had it long enough to note a change in mileage. I got this for my 2016 jeep compass with the 2.0l 4cylinder.

I bought this is hopes of letting my little Jeep patriot breath a little better and give her a little more oomph going down to the sandy beaches of our lake or when trail riding here in the desert. So far so good and she's a little throatier as well. I've noticed a little better peaks on the highway as well as a mile or two difference for the better in gas mileage.

Ordering was very easy. Order was a day early. I will be using K&N products from here on out. I was very pleased.

I have used K&N for years and they still make a very nice upgrade to a car's performance.

One star Tried to order one but you shipped three. Had to spend 20 bucks to ship two of them back and I have been told that I will have to wait three weeks to a month for my refund. Your products may be good, but they aren't that good. I plan to share this experience with as many people as possible. Regarding the likelihood of me purchasing another K&N product??? My answer is, when pigs fly.

OEM fit needed modification ,aside from that steller performance like every other K&N PRODUCT I have bought.
