PFF5-4020BLK Polyurethane Motor Mount Inserts for BMW G22 G23 4 Series

Transform the way your BMW responds with this PFF5-4020BLK Black Series polyurethane motor mount insert set. Designed to occupy the voids in the factory engine supports, these hard-wearing 95A Shore bush inserts rein in powertrain movement for crisper throttle inputs, cleaner gear changes and more immediate power delivery on track and fast road.

Ideal for tuned and hard-driven cars, these inserts slot neatly into the original mounts so you get the control of a competition-grade upgrade without the hassle of removing the OE housings. Expect tighter driveline control, improved stability on and off throttle and a more connected feel from the chassis.

• Fitment: BMW 4 Series G22 and G23, 2020 onwards
• Material: Black Series polyurethane, 95 Shore A

Why enthusiasts choose these poly inserts

• Sharper pedal response and launch consistency
• Cleaner upshifts and downshifts for manual and automatic gearboxes
• More direct torque transfer to the rear wheels
• More composed transitions between throttle on and off
• Helps prolong the service life of original rubber mounts

Installation is straightforward because the inserts are designed to nest into the standard brackets. A small rise in cabin vibration at idle is normal when stiffening the connection between powertrain and subframe. The firmer the compound, the more NVH you should expect.
