BMW X1 F48 F49 2016-on Upper Torque Mount Bush Insert Upgrade - Part No. PFF5-1321

Unlock tighter drivetrain control and a more connected drive on your BMW X1 with this precision-engineered upper torque mount bush insert. Designed for the F48 and F49 platforms, this upgrade limits unwanted powertrain movement without spoiling day-to-day comfort. Ideal for daily drivers and fast road builds looking for cleaner shifts, improved traction out of corners and reduced wheel hop under hard acceleration.

Why enthusiasts choose this upgrade

• Sharper throttle response and more direct gearchanges by stabilising the powertrain under load
• Helps reduce wheel hop and axle tramp, improving off-the-line performance and traction
• Supports the original mount to extend its service life by controlling excess movement
• Balanced NVH for everyday use thanks to a 70A Yellow compound tuned for road and fast road driving
• Simple insert design that fills the key voids of the factory top engine mount for a secure, precise fit
