Powerflex Engine Mount Insert Kit for BMW X3 F25 2009-2017 - Part No. PFF5-4020
Upgrade your BMW X3 F25 2009-2017 with the Powerflex Engine Mount Insert Kit PFF5-4020. These high-performance polyurethane engine mount inserts are the ideal fast road solution to reduce engine movement, sharpen throttle response and improve gear shifting, while keeping NVH to a sensible minimum. Perfect for tuned road cars and daily-driven performance builds looking for a noticeable, bolt-in handling and drivability improvement.
This Powerflex Road Series kit is an intermediate alternative to the stiffer aftermarket full replacement mounts and the factory aluminium inserts. Made from Yellow 70A durometer material, the inserts fit snugly into the voids of the OE engine mounts to control drivetrain movement without the harshness of solid mounts. Cleverly designed so they can be installed without removing the engine mounts from the vehicle.

Real-world results
We have fitted and run these engine mount insert bushes on customer X3 F25 vehicles and feedback has been consistently positive. Drivers report crisper response, cleaner shifts and a more planted feel without excessive cabin harshness. Expect a small increase in NVH, usually at idle. As with any mount upgrade, the harder the material, the more NVH is transmitted, and Powerflex 70A strikes a great balance for fast road use.
