I have used K&N filters for many years because they allow better air flow, burning gas more efficiently- working particularly well with larger engines. It is also good they do not require frequent changing.

First of all, I purchased two K&N Air Filters. One Cabin Air Filter and the other Air Intake Filter. The Cabin Filter, I should have purchased sometime ago. It is well worth paying for it and having the ability to wash it and reusing it over and over is a no brainer, in terms of saving money. The Air Intake Filter, saw a low end increase and definite fuel increase. Again, the idea of washing and reusing the Filter is a definite plus.

Awesome

I purchase the K&N engine and cabin air filters. They are aesthetically pleasing, easy to install, and I've noticed a boost in the horsepower in my vehicle. The best thing of all is that I won't ever have to buy another one for this car. Thanks K&N for making such a great product! I will recommend this to all my friends and when I purchase another vehicle in the future I will also be purchasing K&N air filters.

I have always replaced my stock filter with a K&N filter, going on 7 vehicles now. instant added performance and a little more aggressive engine sound in the higher RPMs. better acceleration too.

My Hyundai Tuscon with 2.4 GDI engine really accelerates better with the K & N filter in place when going up long upgrades and passing trucks. Additionally, went on a 250 mile trip (each way)and got improved gas mileage. Highly recommend it.

I purchased this filter because I have one in my truck and it makes quite a difference in throttle response and gives me better fuel economy. Even though I have heard and read both good and bad reviews of the product. The thing that I have found with these is that they need to be cleaned and oiled on a regular basis. Otherwise, it may not capture all the dust particles it is intended to keep out.
