Replacement Injector Seals

Replacement Injector Seals

Replacement Injector Seals for 94-05 Miata. Kit includes Top O-ring, the rubber piece just below the upper O-ring, and the lower rubber seal that seals the injector into the cylinder head. This lower seal in the head commonly shrinks with age. If you reuse these, they are often a source of vacuum/boost leak. 

We highly recommend replacing these when removing your injectors to prevent any leaks.

Some kits have the wrong size O-rings and can actually result in a leak! Our parts fit correctly, buy with confidence.

Kit includes seals for all 4 injectors!
