Powerflex PFF5-4020 Motor Mount Support Inserts for BMW X3 F25 2009-2017

Unlock a tighter, more responsive drive on your F25 with Powerflex PFF5-4020. This poly bush insert set reinforces the factory engine mounting, controlling powertrain movement for cleaner gearchanges, sharper pedal response and improved traction under load. Ideal for fast-road use on daily-driven cars where you want a noticeable upgrade without the harshness of solid mounts.

These inserts press into the voids of the original engine mounts to reduce drivetrain lash and limit fore-aft movement. The Yellow 70A polyurethane compound is carefully chosen to balance control and comfort, helping to manage NVH while delivering a more connected feel. Installation can be carried out in situ, saving time and keeping costs down.

Why it works

• Controls engine rock for a more direct drivetrain connection
• Crisper throttle pick-up and more consistent shift quality
• Better stability on and off throttle for confident road driving
• Supports ageing OE mounts to help maintain performance
• Quick fitment into the stock mounting voids

Proven on customer cars

We have fitted these to multiple X3 F25 vehicles and the feedback has been consistently positive. Drivers report a more planted front end, reduced shunt on take-up and a tidier shift without an intrusive increase in cabin vibration. Expect a small rise in NVH at idle, which is normal for any mount upgrade.
