The NeedsWing CA intake is too much $ for the benefits you get, cosmetic only in my mind, but it is your money.
A larger Mercedes air box is available and along with a larger throttle body from a SRT and a matching MAF housing using the original MAF sensor is about the best you will do.
Do not expect to reach 200hp at the rear wheels on a dyno, more like 195.
The car will feel a bit livelier at higher speeds, the spotty faced kid in his Honda will still wave you goodbye at the lights, you can do the same to him when you get going.
That’s my thoughts anyway, you did not buy a fast car, good freeway cruiser though.
