If you are not installing our rebuilt injectors, we highly recommend this seal kit any time you remove the injectors from the manifold. Yours are beyond crispy and could be creating a vacuum leak (rough idle, high idle, lean running...etc). All 3 of the seals on the injector should be soft an pliable.
Seal kit includes upper o-ring, upper cushion and the lower injector to manifold seal.
*already installed on our injectors, so if you are buying those, no need for these.
