Part number: PFF5-4650

Quantity in kit: 2 bushes with tuneable pins

Transform the way your BMW E46 3 Series Compact responds with this pair of Powerflex polyurethane motor mount bushes. Designed for enthusiasts who want crisper throttle pick-up, tidier gear changes and greater drivetrain stability, this tuneable mounting solution lets you dial in firmness for fast road or circuit use using the supplied adjuster pins. If you are searching for E46 Compact motor mounts, polyurethane engine mounting kit, uprated powertrain mounts, drivetrain stabiliser bushes or performance mount inserts, this is the upgrade that delivers.

Built from Powerflex’s proven high-performance polyurethane, these mounts control engine movement far more effectively than tired OE rubber while remaining civilised for daily driving when set up with fewer pins. With increased support under load, you get more consistent handling, better traction on corner exit and a noticeably more connected feel. We run these on our own builds at MJ Modifications and customer feedback has been outstanding for both spirited road use and trackdays.

Why this upgrade makes sense

• Rivals OE rubber for NVH control when configured softly, with far better resistance to collapse under load
• Excellent for remapped cars, track-prepped builds and drivers who want a tighter, more predictable front end
• A fit-and-forget solution that resists oil, heat and ageing better than standard rubber mounts
