Alfa Romeo Giulietta 940 (2010 - 2020) Lower Engine Mount Bush Insert - PF1-1020BLK Insert for the original bush. An increase in noise and vibration is to be expected. This should be considered as a performance upgrade, not a standard replacement. Our polyurethane insert kit ships with a bolt spacing sleeve made using our Shore A 95 Black material to take up the excessive tolerance on the bore of the original mount to further reduce engine movement under load. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
