Powerflex PFF5-4020 Poly Motor Mount Inserts for BMW G32 6GT 2017+

Transform the way your BMW G32 6 Series Gran Turismo responds on the road with Powerflex PFF5-4020 polyurethane motor mount inserts. This Road Series Yellow 70A upgrade supports the standard rubber mounts to control engine rock under load, giving you cleaner shifts, sharper throttle pick-up and a more connected feel without sacrificing day-to-day refinement.

Ideal for fast-road use and remapped cars, these inserts are the sweet spot between soft factory mounts and full solid replacements. They stabilise the powertrain so more of your torque reaches the tarmac, reducing driveline shunt and improving consistency on and off the throttle.
