For the money it is a great buy for this car, I have bought these before but on this vechicle, I actually notice throttle response is better, gas mileage, and it has a small but noticeable throaty sound to the intake now

This air filter is easy replacement/upgrade in the GLC300...two screws, pop out the original, and throw in the K&N. Took me all of 10 minutes to do it. My wife says now when she steps on the gas to merge on the highway it sounds very sporty. It now has an intake growl and before it was non-existent. I cannot say if there are additional power without using a dyno nor can I say I am getting better gas mileage since my wife has been pounding the pedal to hear the intake growl. :-)

K&N as usual did not disappoint me. Speedy shipping, great value and a performance upgrade that could be done within minutes. Huge savings on fuel consumption and awesome performance increase. Totally recommended for Mercedes W205 2.0.

The rubber of the frame was too tight to close the filter lid at first, so it took some time to install. I hope there is a boost on performance since the car is accelerating good.
