Powerflex Black Series Poly Engine/Motor Mount Insert Bush Kit for BMW X4 F26 2013-2018 | Fast Road & Track | PFF5-4020BLK 95A

BMW F26 X4 2013-2018 Polyurethane Motor Mount Bush Inserts — PFF5-4020BLK

Transform throttle response and driveline precision on your BMW F26 X4 with this competition-grade polyurethane mount upgrade. Part number PFF5-4020BLK is a Black Series 95 Shore A poly insert set engineered to locate into the cavities of the factory engine mounts, tightening up movement under load for a sharper, more connected drive on road and track.

Unlike full replacement solid mounts or solid alloy inserts, this solution gives you serious control and feedback while retaining the original mount body. Installation can be carried out in situ on the vehicle, so you gain performance without the hassle of removing the entire mount assembly.

• Crisper throttle feel and more immediate response when you get back on the power
• Clean, confidence-inspiring gear changes with reduced powertrain rock
• More direct power delivery to the wheels for stronger acceleration
• Composed on and off throttle transitions for balanced handling
• Supports and prolongs the life of the original equipment mounts

We have fitted these bush inserts ourselves and our customers love the difference. It is a smart middle ground between standard mounts and hard solid options, ideal for fast-road builds and track-day cars looking to reduce engine movement and tighten drivetrain control.

Important information

Using stiffer mount inserts can increase noise, vibration and harshness, typically most noticeable at idle. The firmer the compound, the more of this you may experience. This Black Series upgrade prioritises control and performance.
