Audi A3 / S3 / RS3 A3 / S3 8L (1996-2003) Front Engine Mount Dog Bone (Petrol/Tuned Diesel) - PFF85-420H Made in our Grey 70A material, PFF85-420 is intended for petrol or tuned diesel vehicles. For significantly tuned petrol or diesel vehicles, or those being used on track, please use PFF85-420BLK. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mounting between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted. Please have a look at this quick guide on how to fit PFF85-420 and associated part PFF85-505 - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
