A CLASS W176 INC. A45 AMG (2012-2017) - ROAD SERIES
- PFF40-120 & PFF40-121 fit petrol & diesel models. They are both an insert to fit into the original mount to limit movement of the engine to provide stability under acceleration. If fitting this to a diesel engined vehicle, an increase in noise and vibration is to be expected. This should be considered as a performance upgrade.
