Fuel Injector O-Ring Combo Kit - 2006-2013 Mazdaspeed DISI 2.3

Keep the fuel leaks and misfires away with brand new Mazda O-rings for your fuel injectors! This kit replaces the blue o-rings and the backup rings for the tops of the injectors on your Mazdaspeed 3, 6, or Mazda CX-7. As these vehicles are showing their age, it is becoming more common for these seals to become damaged, especially when removing or reinstalling the fuel rail. This kit replaces all four components that comprise the seal between the injector and fuel rail on all four injectors.

NOTE: this kit does not include the seals between the injector and the cylinder head, but you can purchase them HERE!
