Swirl Flap Delete Plugs — Mercedes OM642 3.0 V6 Diesel | Aluminium | OEM 6420903237 | Off-Road Use
Eliminate the #1 Engine-Killer on OM642 Diesels — Before the Flaps Destroy Your Engine.
The swirl flaps in Mercedes OM642 3.0L V6 diesel intake manifolds are a well-documented failure point — plastic holder bolts shear, flaps break off, and fragments enter the engine. These aluminium delete plugs (OEM 6420903237) permanently seal the swirl flap shaft holes, eliminating the failure risk before it causes catastrophic damage.
Important: Swirl flap deletion is intended for off-road use or markets where emissions modifications are permitted. ECU remapping is recommended. Verify local regulations before purchase.
Note: Exercise caution when removing swirl flaps — inspect for broken fragments before installation.
