I need the top O-ring for one of mytt225 injectors. These at ECS Tuning say they fit the upper and lower section of the fuel injector but doesn't state what type of injector it fits. Also, my upper O-rings are larger than the bottom section so I don't see how that would be true. Anyone know if it will fit or if there's a better place to purchase this?? thanks

 

They have the same part number for both the top and bottom o-rings so you should be ok to install them, hey if not you'll know in a hurry lol!

 

haha yeah no kidding. But I actually have the injectors in front of me and took the o-rings off and they are substantially different so they can't be the same part number. I'll give Audi a call tomorrow; hopefully they'll carry them.
