It makes sense to choose with care the replacement parts for your Porsche - the same care you used to choose your Porsche in the first place. Genuine Porsche parts provide quality and reliability you can depend on. Just like the cars, Porsche parts are subjected to some of the most rigorous testing procedures in the industry. Of course, Porsche's renowned endurance racing efforts have also proved to be an outstanding test bed for parts durability: nowhere else are parts and components subjected to higher levels of stress. And no manufacturer uses more race-proven parts and engineering than Porsche.
