Powerflex Engine/Motor Mount Insert Kit for BMW X7 G07 (2018+) – PFF5-4020 Yellow 70A Polyurethane Fast-Road Poly Bushes/Bushings, Torque Mount Insert, Drivetrain/Engine Support Stabiliser/Stabilizer, Void Filler Upgrade

Powerflex Motor Mount Insert Set for BMW X7 G07 2018 onwards - PFF5-4020

Take the slack out of your BMW X7 G07 powertrain with this Powerflex PFF5-4020 motor mount insert set. By filling the voids in the factory engine supports, these polyurethane inserts stabilise the drivetrain, reduce unwanted engine rock and deliver a more connected, precise driving feel on the road.

Manufactured in Powerflex Yellow 70 Shore A polyurethane, this fast-road compound sits perfectly between soft OEM mounts and overly aggressive solid solutions. Expect crisper throttle response, tighter gearchanges and better power delivery to the tyres, with only a small increase in noise, vibration and harshness at idle.

• Reduces engine movement for cleaner launches and quicker response
• Improves shift precision and driveline engagement
• More consistent torque transfer and traction under load
• Helps limit mount fatigue to extend OE mount life
• Typically installs without removing the original mounts

Why this upgrade works

The X7 G07 uses voided rubber supports to isolate vibration. Under acceleration and on-off throttle, those cavities allow excess movement that you feel as shunt and lag. PFF5-4020 infills those cavities, controlling motion while maintaining daily comfort. It is the smart, value-packed alternative to full replacement mounts if you want sharper response without harshness.

Tried, tested and loved by our customers

We have fitted this kit on our own vehicles and numerous customer X7s with consistently excellent feedback. Owners report a tighter front end, reduced driveline lash and a more confidence-inspiring feel on spirited B-road drives and everyday commutes alike.

Track-focused option

Chasing maximum control for circuit use. Powerflex also offer a Black Series compound at 95 Shore A for dedicated track and motorsport applications. As expected with the firmer material, NVH increases.

Fitment and installation

Designed to press into the factory engine mount voids on BMW X7 G07 models from 2018 onwards. Installation is straightforward and can typically be completed without removing the mounts from the car.
