Intake Manifold Swirl Flap Rod Pin Set – Mercedes OM642 3.0 V6 Diesel (2 pcs) | OEM A6420905037
The intake manifold swirl flap rod pins on the Mercedes OM642 3.0L V6 diesel are a critical wear component. When they break, the swirl flap rod detaches and fragments can enter the intake — causing catastrophic piston and valve damage. This 2-piece set (left and right manifold) replaces the pins before failure occurs.
Fits OEM #A6420907737.
