K&N 33-5050 Air Filter Product Reviews

Bought this for my 2017 Hyundai Elantra with the 2.0L eng. Works great, adds more HP. Note: it does make the engine louder.

This is my 5th K&N filter and again it is performing better than I had expected. I just purchased a 2017 Hyundai Elantra. On the highway, I typically average 3-5mpg better than the manufactures rating. This is definitely a worthwhile investment. I would highly recommend.

This is probably my 10th K&N product. They never fail to produce excellent results. New 2017 Hyundai limited. Engine idle dropped to 500rpm from 900rpm. Averaged 42 MPG @ 75mph. Noticeable improvement in torque and midrange power.

Better High Speed Power. In my 2017 Hyundai Elantra 2 Liter Four. I Have used these in my new cars for years. I am more than happy with K&N filters.

Great replacement, can tell a huge difference in power over stock filter.
