Intake Manifold Swirl Flap Repair Kit – Mercedes M272 / M273 | Aluminum Upgrade

The swirl flaps inside the Mercedes M272 3.0/3.5L V6 and M273 5.0L V8 intake manifolds wear loose over time — causing P2004/P2006 fault codes, intake rattle, and rough idle. The original plastic flap inserts are the failure point. This aluminum upgrade kit replaces them with precision-machined aluminum components for long-term reliability.

Fits OEM #A2721402401.
