Review: Fits my Mercedes W203 perfectly! - What is not to like? I bought this for my 2006 Mercedes C280 W203, it worked perfectly and looks exactly like the original. Easy to install if you follow directions to remove the electrical harness, fuel injection rail and intake manifold. Once these are lifted up, the part goes under where the intake manifold was seated. Easy to pop off the old one and slip the new one on, then reverse the order to replace everything back. You are now ready to go!
