This Powerflex Black Series upper engine mount bushing is a firmer, 95A-durometer polyurethane insert that stiffens the factory oil-filled upper engine mount, reducing engine movement under load for sharper throttle response and crisper gear changes. As a race-durometer Black Series part, some additional NVH (noise, vibration, harshness) versus the standard Street version should be expected; it is backed by Powerflex's lifetime warranty.
Fitment: MINI Cooper and Cooper S, R50/R52/R53 chassis (2001-2006).
