I am glad crossfire owners are aware of this booster i have it on both my SLKs (320 & 350) and will be installing it on the crossfire.

Opening the hood of the crossfire i am always at home but at less than half its price. great car.

There is a huge difference in the acceleration responses when this thing is installed. NO lagging, which is typical of the mercedes engines we have.
