PFF5-4020 Poly Insert Bushes for BMW X6 G06 2019 onwards

Give your BMW X6 G06 a tighter, more connected feel with Powerflex PFF5-4020 motor mount insert bushes. This upgrade fits into the voids of the factory rubber mount to control powertrain movement, delivering sharper pedal response, cleaner upshifts and downshifts, and more immediate power delivery without resorting to harsh solid mounts.

Manufactured in Powerflex Yellow 70A polyurethane, these inserts act as a void filler for the standard mount, limiting engine rock under load while keeping cabin refinement intact. Ideal for daily-driven and tuned road cars, fast road builds and anyone seeking a more planted, precise BMW X6 G06.

What you will feel

• Faster tip-in and more consistent acceleration response

Real-world results

We have installed these inserts for multiple customers at MJ Modifications and feedback has been consistently positive. Owners report a more responsive front end, a calmer drivetrain under hard acceleration, and a noticeable reduction in unwanted movement during spirited driving, with only a slight increase in idle vibration that most find completely acceptable.

Install and NVH

PFF5-4020 is designed to slide into the cavities of the original mount, so the mount can stay on the car. Expect a small rise in vibration, largely at idle, proportional to the added control. For road cars this is typically very mild compared with the handling and response gains.

Track-focused option

Building a more hardcore setup for circuit use or time attack The Powerflex Black Series equivalent uses a stiffer 95A compound for maximum control and is intended for motorsport environments.
