Audi TT Models TT / TTRS Mk3 FV/8S (2014 on) Upper Gearbox Mount Bush Insert - PFF3-1322 PFF3-1322 Upper Gearbox Mount Insert is made in our Yellow 70A durometer and is designed to fill the voiding present in the original rubber mounts. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: - Sharper throttle response - Reduced wheel-hop - Improved Traction - More balanced on/off throttle handling - Prolonged the life of the OE mounts - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
