Mercedes-Benz M272 & M273 Intake Manifold Common Problems | 603 MTech Autowerks 

Damn you guys are the truth saving Benz owners with these videos

Full replacement is always the best policy, I have seen several with the flaps that came apart inside. Thanks for the video.

Good video.

I miss my w212 e550. M273 was a beast

Hello sir, could you do some overview video about M273 engine only? Thx

Replace the intake with an M113 whipple blower and M113 to M273 adapter plate
