Honda CR-Z (2010 - 2016) Lower Engine Mount Bush Insert - PFF25-820BLK Made in our 95A durometer material for ultimate track/motorsport performance, it is a cost-effective and easy-to-fit insert, designed to sharpen throttle response; whilst reducing wheel hop and improving the durability and longevity of the OE mount. An increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine 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!
