The BOIGEVIS High Quality Engine Mount (OE No. 1672405400 / A1672405400 / 167-240-54-00) is a front-right hydraulic engine support built for Mercedes-Benz W167 GLE450 4MATIC and X167 GLS450 4MATIC with the M256 3.0L inline-six mild-hybrid (EQ Boost) drivetrain, covering model years 2020–2024/2025.
Manufactured to OEM-equivalent bracket geometry, bolt pattern and rubber-to-metal bonding, it secures the engine while isolating idle shake, cold-start shudder and road shock from the cabin. The unit uses a temperature-resistant elastomer with anti-corrosion metal shell and a hydraulic chamber tuned to the M256 combustion and ISG load profile, clearing clunk-on-shift, dashboard buzz, PDM “mount plausibility” faults and premature surrounding-component fatigue caused by a collapsed original mount.
Each BOIGEVIS mount is load-cycled, leak-checked and dimensionally verified against A1672405400, with the left-side counterpart A1672405300 (1672405300) available for paired replacement. Aimed at Mercedes-Benz collision and suspension/drivetrain workshops, fleet servicers and export distributors, it delivers genuine-level damping at aftermarket cost, with BOIGEVIS warranty and container shipping from its Guangzhou warehouse. Confirm side (right vs left) and VIN before order; professional lift installation with torque-spec hardware is recommended.
