Rover 400 & 45 HH-R (1995 - 2005) Engine Mount Stabiliser Large Bush (Diesel) - PFF63-418R PFF63-418R and PFF63-419 suit both the Upper and Lower engine stabilizers, hence being 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. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
