Fiat 500L (2012 - ) Upper Engine Mount Insert - PFF1-1125BLK This 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 and throttle application by stiffening and supporting the often perished rubber, a common failure on tuned vehicles. This supports a more precise and settled transmission response during acceleration and deceleration. This new part combines perfectly with our other Upper Gearbox Mounts and Lower Gearbox Mounts for greater engine stability. 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!
