Powerflex PFF5-4021 Motor Mount Insert Pair for BMW F87 M2 2015 onwards

Unlock a tighter, more connected drive on your F87 with the Powerflex PFF5-4021 motor mount insert set. This street-focused polyurethane upgrade fills the voids in the factory engine mounts to curb unwanted movement, delivering crisper throttle pick-up, more precise gearchanges and cleaner power delivery without sacrificing day-to-day comfort. Ideal for fast-road use and tuned road cars that demand better drivetrain control.

Real-world results you can feel

We fit these inserts on our own builds and customer cars at MJ Modifications and the feedback is consistently positive. Drivers report a noticeably more direct connection to the powertrain with only a small increase in cabin NVH, typically at idle. It is the sweet spot for daily-driven performance and spirited weekend use.

Installation and support

The inserts are engineered to slide into the voids of the standard mounts, so in most cases the mounts do not need to be removed from the car. A modest rise in noise, vibration and harshness can be expected when stiffening the connection between the engine and chassis. The firmer the material, the greater the potential NVH at idle.
