Has anyone else got these stupid plastic blockers in their intake path? I've looked at photos of other M278 engines and don't see these things. Why would they put them on the CLS?
I think I will pop them out... it seems they are held in place with a simple plastic grommet. Very strange that Mercedes would put these in the intake path.
Group buy for all you interested folks including myself! I was going to wait until black friday for a sale and to familiarize myself with this engine (M157) before any performance mod, but these helped my s55 breathe much better on top of pulley/tune mods.
