Powerflex Lower Engine Mount Bush Insert PF1-1020BLKInsert 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.
