Vauxhall / Opel ASTRA MODELS Astra MK6 - Astra J (2010 - 2015) Rear Engine Mounting Insert - PFF80-1421BLK This part is designed to fit into the original voided rubber mount which degrades and softens over time, allowing for excessive movement of the engine and premature failure. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
