Audi A3 / S3 / RS3 A3 / S3 / RS3 8V (2013 - 2020) Upper Engine Mount Bush Insert - PFF3-1323 PFF3-1323 Upper Engine 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!
