Mercedes M272 & M273 — Runner Flap Repair, Induction & ECU Tuning

Parts for the Mercedes M272 3.5L V6 and M273 5.5L V8 — two engines that share the same well-known intake manifold weak point.

Throwing P2004, P2005 or P2006?

That's the intake manifold runner flap actuator — a small plastic linkage that fails on both the M272 and M273, causing rough idle, lost low-end power and a check engine light. If your flaps still move freely, the air flap adjuster repair kit below is the cheaper and more sensible fix.

Also here: custom ECU tuning for both platforms, high-flow drop-in air filters from K&N and aFe, X-pipes, and long-tube headers.
