K&N Cold Air Intake Kit: 2012-2018 MERCEDES BENZ ( CLA250, A160, A180, A200, A220, A250, CLA180, CLA200)57S-6200

Just installed this very well-made intake in my 2014 CLA. Installation was simple and straight-forward, and all necessary hardware was included. A few installation notes: 1) have the .pdf of the installation instructions available on your device, as the printed pictures that come with the kit are, at times, not very helpful; 2) the instructions suggest a utility knife for cutting the rubber gasket/seal - I had in my toolbox, and suggest, using a medium tin snip, as it makes cutting the bit of metal in the seal strip very easy; 3) do all the set-up of the intake first (mounts, rubber seals, logo plate, filter, ECU) before you remove your stock intake. In my opinion this will make installation more enjoyable, as you can do all this from the comfort of your LA-Z-BOY. The ECU moves from the side of the stock intake to the bottom of the K&N intake. Be gentle as you manipulate and re-route the ECU wiring harness, but don't fear - fitment is perfect. You'll also notice this intake takes advantage of both of the air inlets at the front of the engine bay, whereas the stock intake uses only one. Fire it up! Idle exhaust note is subtly deeper and louder. WOT in Sport is very satisfying, both in exhaust note and power improvement. ECO mode improvement is very much there as well. I can't quantify the power increase, but my backside feels it. And if you enjoy some turbo whine that was lacking with the stock set-up, you've got some now.

Yo, this Air Intake has changed the tone of the exhaust, AND I LIKE IT! The turbo whistles now in stereo for the very 1st time. The power increase is noticeable and In my opinion the K&N Performance Air Intake is well worth the $$$.
