Toyota Supra Mk5 A90/J29 (2019 -) Engine Mount Insert - PFF5-5452 PFF5-5452 Engine Mount Insert is a two-piece kit made using our Red 65A durometer material, designed to fill the voiding of the OE rubber mount to limit drivetrain movement and sharpen throttle response on standard or mildly tuned vehicles. Mount rigidity is increased by 100%. 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. Fits 3.0ltr B58 engines only. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
