Powerflex BMW F82, F83 4 Series M4 Engine Mount Insert Kit

• Developed for ultimate performance using the toughest materials
• Engineered for the most accurate control of chassis geometry
• Manufactured to be easily fitted without the need for special tools
• Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry.
• This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material.

• We are pleased to introduce PFF5-4020 and PFF5-4021 Engine Mount Insert Kits, intermediate alternatives to the BMW aluminium inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in our Yellow 70A durometer material, they are designed to fit the voiding of the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: - Sharper throttle response - Improved gear shifting - More direct power transfer - More balanced on/off throttle handling - Prolonged life of the OE mounts. A small 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.
