Vauxhall / Opel ASTRA MODELS Astra MK5 - Astra H (2004 - 2010) Upper Right Engine Mounting Insert Diesel - PFF80-1322BLK Designed to fill the voiding in the OE rubber mount, it smooths out gear changes and throttle application by stiffening and supporting the often perished rubber, a common failure on tuned vehicles. This provides a more precise and settled engine response during acceleration and deceleration. A small increase in NVH, typically at idle, should be expected when stiffening the connecting mount between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
