Powerflex PFF5-1321 Polyurethane Top Engine/Torque Mount Insert Bush for BMW X2 F39 (2017-on) – Upper Motor Mount Bushing Upgrade, Engine Mount Insert | Road Series

Top Engine Torque Mount Poly Insert for BMW X2 F39 (2017 onward) — Part No. PFF5-1321

Unlock sharper drivability and longer mount life on your BMW X2 with this high-quality polyurethane insert. Designed specifically for the factory top motor mount on the F39 platform, this rod‑style insert fills the voids inside the original mount to control drivetrain movement under load. The result is cleaner upshifts, more direct throttle response and reduced wheel hop, while remaining perfectly usable for everyday road use.

Manufactured in Powerflex’s Yellow 70A polyurethane, this insert offers a street-friendly balance of stiffness and comfort, making it ideal for standard and remapped 2.0 turbo models looking for a tighter, more connected feel without going full solid.

Why choose this poly insert

• Improves shift precision and driveline response during acceleration and lift-off
• Cuts unwanted engine rock, helping to tame wheel hop and traction loss
• Supports and extends the life of the original mount by reducing excessive movement
• Road Series specification for daily driving and fast-road use
• Durable, oil- and heat-resistant polyurethane construction
• Simple, cost-effective upgrade with a big feel difference
