Powerflex Black Series Track/Performance Engine/Motor Torque Mount Insert Bush/Bushing Kit (95A) for BMW 5 Series F10/F11 2010-2017 – Polyurethane Void Filler – PFF5-4020BLK – Replaces 22112284817 22112284818

Uprated Motor Mount Poly Insert Set for BMW F10 and F11 5 Series - Part No. PFF5-4020BLK

Unlock sharper response and tighter drivetrain control on your BMW 5 Series F10 and F11 with this Black Series polyurethane mounting insert set. Manufactured in a 95 Shore A compound, these precision moulded pieces fill the voids in the factory rubber motor mounts to curb engine rock, stabilise the powertrain and maximise the connection between the engine and chassis. Perfect for tuned cars, circuit use and enthusiastic driving where consistency and feedback matter.

We run these inserts on our own builds and customer cars, and the feedback is consistently positive. Expect crisper throttle pick up, cleaner gear changes and a more direct transfer of torque to the wheels.

Why choose this poly insert upgrade

• Fills OE mount voids to limit powertrain movement without the cost of full replacement mounts
• Black Series 95A material for maximum control of chassis geometry on track
• Install can be completed without removing the mounts themselves, saving time and hassle
• A smart middle ground versus solid alloy inserts or ultra-stiff complete mounts

Real-world benefits

• Faster throttle response and improved drivability
• Slicker shifting with reduced engine twist under load
• More immediate power delivery and better traction on corner exit
• More balanced handling during on and off throttle transitions
• Helps prolong the life of the original rubber mounts
