Suzuki Swift Sport MK2 (ZC31S) (2006 - 2010) Gearbox Mount Front Bush Insert - PFF73-303 Fits European models only. This insert is made in our Yellow 70A durometer material for increased transmission mount longevity and performance on Petrol or tuned Diesel engines. 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. 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!
