My 06 c350 4matic is getting tweaked by renntech next week when i send it. When that happens ill have 290 hp. I wanna get to 300 hp.anybody have any ideas of what else i can do? I was thinking cold air intake or new air filter possibly? any suggestions? thankssss

I guess header and exhaust system should do it. By the way, how does 290hp feel compared to before?

Go to mbjunkies and look up Cales build thread. He has larger tb and single runner intake manifold, headers, retune, exhaust and is pushing pass 300 I believe. All the tb and manifold is from other model mb s500 I believe
