This kit is designed to save you time when installing your accessory belt tensioner by providing new correct hardware. Now you wont have to worry about damaging the old bolts if they take a little bit of excess force to remove. On top of that, now you will have clean new bolts holding in your clean new tensioner.
* This kit is designed for the FSI engine only. This can easily be found on the engine cover of your 2.0T VW/Audi. It will clearly be stamped FSI (not TFSI).
