Powerflex Black Series Poly Engine/Motor Mount Insert Kit for BMW X6 F16 (2015-On) PFF5-4020BLK – Engine Bush Upgrade, Transmission/Gearbox Mount Support, Track Day Poly Bushings

Unlock sharper response and tighter drivetrain control on your BMW X6 F16 with this polyurethane motor mount insert set. Part number: PFF5-4020BLK.

Built from race-grade polyurethane in a firm Shore A 95 compound, this insert kit fills the voids in the original engine supports to limit movement under load. Ideal for performance builds, remapped cars and regular track-day use, it gives your X6 a more connected feel without the need to replace the factory mounts.

Why enthusiasts choose this upgrade

• Quicker throttle pick up and a more immediate pedal feel
• Cleaner, more precise gear changes
• Stronger power delivery with reduced drivetrain shunt
• Improved stability on and off the throttle during hard cornering
• Helps protect original mounts by limiting excessive engine rock

Installation is straightforward. The inserts are designed to fit with the mounts in situ, so there is no need to remove or press out the OE parts. Expect a slight increase in NVH, most noticeable at idle, which is normal for a focused performance insert of this hardness.

Track-focused material, road-ready results

This Black Series specification uses a tough polyurethane blend for maximum control of engine movement. It is a popular choice on our customer builds, delivering consistent results and excellent feedback for fast road, circuit and motorsport use.
