Lower Rear Engine Mount Insert

PFF1-1120BLK

For C510.5 and C514 gearboxes. For models with TCT gearbox, use PFF80-1120. This part is inserted into the original bush, to increase stiffness. If fitting this to the Diesel or TwinAir engine vehicles, an increase in noise and vibration is to be expected. This should be considered as a performance upgrade.
