Fits European models only. 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.
