Powerflex Front Engine Mount Bushing Insert - Street - PFR57-521

Porsche Boxster and Cayman factory front engine mount bushings are particularly prone to cracking because of the large amount of voiding in the rubber material.  If left unchecked, the rubber will continue to wear and knocking sounds may appear as you accelerate, brake and turn. Gear changes also become sloppy and lose precision.

The Powerflex Front Engine Mount Bushing Insert is a solution to prevent failure of the factory part.  If your stock bushings are in poor condition see our engine mount bushing replacement (bottom of page) which will replace and improve the factory bushing design.
