Porsche Boxster/Cayman (981 & 987.2) Front Engine Mount Bushing

PFR57-820 fits all models from 2009 onwards. For any models before this, please use PFR57-520.

However, according to specialists and those in the know, suspension problems are the second most common reason for a 981/987.2 to fail its MOT and the same fatigue seen in the rubber suspension bushes, can be seen in the engine mountings.

Prolonged and repetitive strain translated through the engine mounting in combination with the large voiding in the OE bush, results in accelerated ageing of the rubber, with bush failures often seen from around 50,000 miles onwards.

PFR57-820 Front Engine Mount Bush is made from our Yellow 70A durometer material and supplied with an anodised outer shell and supporting washers, providing a 20% increase in stiffness over the standard rubber, suiting all 981/987.2 models from 2009 onwards.

A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted.
