Peugeot 107 (2005-2014) Lower Engine Mount Bush Insert - PFF12-721 Suitable for petrol models only. This is a polyurethane insert to fit into and fill the voids in the original mount. It is designed to limit movement of the engine to provide additional stability under acceleration. For a complete, replacement bush please use PFF12-720. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
