PFF5-1321 Upper Engine Mount Insert are a simple, but effective rod design made from our Yellow 70A material. They fill the key voided areas of the mount to restrict engine roll, providing the perfect balance of compliance and rigidity, making them ideally suited for your daily driven vehicle. As the vehicles age and simple upgrades seeing  the  2-ltr  turbo engine push power north of 250bhp, the OE rubber  engine and transmission mounts are showing their age, with cracked rubber and  excessive movement.  Designed  to fit within the  voiding of the original mount, these new  inserts  prolong the life of the OE mount by stiffening and limiting movement of  the  rubber. This results in a more  settled transmission response  during acceleration and deceleration, improving gear changes and reducing  wheel-hop.
