Powerflex PFF5-4020 Engine Mount Insert Kit for BMW X5 G05 (2018-on) - Yellow Polyurethane 70A, Set of 2

PFF5-4020 Motor Mount Bush Kit for BMW X5 G05 2018 onwards

Give your BMW X5 G05 a tighter, more responsive feel with this PFF5-4020 performance motor mount insert set. The Yellow 70 Shore A polyurethane compound acts as a void filler for the factory hydraulic mounts, curbing engine rock and helping the powertrain stay planted under acceleration, braking and quick gearchanges. Expect crisper pedal response, cleaner upshifts and downshifts, and reduced driveline shunt without turning your daily drive into a chore.

These precision-moulded bushes slip into the existing mount voids, so they can be installed with the mounts still on the vehicle. It is the ideal street-friendly upgrade that sits between simple alloy plug solutions and very stiff full replacement mounts, delivering a balanced improvement in control with only a small increase in cabin vibration, most noticeable at idle.

• Fitment: BMW X5 G05, 2018 on

What you will feel

• Less engine movement and tighter powertrain control under load
• Quicker throttle reaction and more direct power delivery
• More precise gear changes with reduced on off throttle lash
• Improved longevity of the factory hydro mounts by limiting excessive deflection
• Simple install with the mounts in situ

Note on refinement: firming up the connection between the engine and subframe can add a slight increase in vibration and noise. The harder the compound, the more NVH you will notice.

Track focused alternative

For dedicated circuit use, a stiffer Black Series 95 Shore A option exists for maximum control of powertrain movement. It is aimed at motorsport where ultimate precision takes priority over comfort.
