PFF5-4650 Uprated Motor Mounting Bush Kit for BMW E46 3 Series

Part number: PFF5-4650
Diagram reference: 50
Quantity in kit: 2 bushes

Give your E46 a sharper, more connected feel with this performance motor mounting bush kit. Built from performance polyurethane, PFF5-4650 replaces tired OE rubber to curb unwanted powertrain movement, tighten drivetrain control and help your 3 Series put power down with confidence on B-roads, sprint events and track days.

This tuneable solution is supplied with adjuster pins so you can set the firmness to match your build. At 5 mm compression, the mount rates at just under 200 percent stiffer than standard. Install all four pins and stiffness rises to just under 300 percent over stock for maximum response when you need it.

  • Performance motor mount bushes designed for BMW E46 3 Series, including Touring
  • Tuneable stiffness via included adjuster pins for road, club sport and track-day setups
  • Helps reduce drivetrain wind-up, engine rock and imprecise handling caused by ageing rubber
  • Improves steering feel and traction consistency under acceleration, cornering and braking
  • Durable polyurethane resists oil, heat and degradation for long-term, consistent performance
  • Backed by the Powerflex Lifetime Warranty

Why enthusiasts choose PFF5-4650

Correctly formulated polyurethane controls movement without the soggy, inconsistent feel of worn factory mounts, while maintaining excellent noise and vibration refinement for daily use. We run these on our own builds and customer feedback has been consistently positive on response, stability and durability.
