MG ZR (2001 - 2005)Engine Mount Stabiliser Bush (Small)PFF63-419 does NOT fit V6 petrol models. PFF63-418 and PFF63-419 suit both the Upper and Lower engine stabilisers, hence why it is listed as 2 per car for each bush. 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, not a standard replacement.
