This is my second vehicle using K&N and having not to worry about keeping up with the extra maintenance is a blessing but the extra performance and horsepower is nice to have as well. Thanks K&N!

Just bought GS brand new. Swapped out new filter and instantly felt a difference. Quicker throttle response and like this wasn’t the most “cheesin” ride out there already. With my new KN in my Buick GS there is a racetrack at every stop sign. 😁😁😁😁😁

K&N are very consistent in the products they make. The filter for the GLC300 was smaller in height of fins than the OEM Mercedes filter... I always change out to a K&N with every car I buy.

It was a god switch from the stock filter I had from when I originally bought the car. It was super dirty from the 40k miles I put on while driving. On the highway can’t wait to see the difference.

I have been a long-time user of K&N air filters for all my vehicles. Having a perceived performance increase is the primary goal while being environmentally responsible is an added bonus. This filter fit our Honda Accord as well as the original. Being a brand new car it is more difficult to discern the benefits, but I am certain the vehicle will operate better than with the standard OEM filters it came with. Very satisfied with the purchase of this K&N filter.

K & N is a brand I'ved used for years in my truck, but this is the second one in my cars. I like the quicker throttle response from improved air flow.

Perfect fit, I noticed the immediately in the performance and about 1 mpg improvement on the highway. This filter from K&N is what I have come to expect from K&N.

The factory air filter was made with locking tabs on the left and right side to hold the filter in place - the K&N version did not have any locking tabs, instead a nylon pull tab was used. The filter was also a bit more snug than the factory filter, but it did seat in well enough to close up the filter compartment. I've noticed about 1 mpg savings on gas mileage...I'll take that all day long for 30 seconds worth of work.
