Alfa Romeo MiTo (2008-2018) Upper Gearbox Mount Insert - PFF1-1130BLK PFF1-1130BLK Lower Engine Mount Insert is made in our hardest Black 95A durometer material for heavily tuned vehicles and track use for maximum strength and response. Designed to fill the voiding in the OE rubber mount, it smooths out gear changes by stiffening and supporting the often perished rubber bush, which is common for failure on tuned vehicles. This will provide a more precise and settled transmission response during acceleration and deceleration. A small increase in NVH, usually 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!
