GB Manufacturing Mazdaspeed Injector O-Ring Seal Kit

The GB Manufacturing Mazdaspeed Injector O-Ring Seal Kit includes the necessary seals and o-rings for properly resealing the injector. It is highly recommended to service the injector every time it is removed, as blown out seals can cause issues such as power loss and false knock. The kit also comes with 4 sets of fuel rail side seals and OE style combustion side injector seals (not shown). To eliminate any potential issues, we suggest not using the OE combustion side seals and using Overspeed Injector Seals instead.

For added performance and serviceability, we recommend our Injector Stud Kit.
