Bosch EV14 style Manifold Side Injector Adapters
These adapters allow secure injector fitment into the injector counterbore of your B/D/H series intake manifold. These adapters push into your manifold and seal against the manifold with an o-ring. The inside bore of the adapter is 14mm and lets the o-ring of the injector create an airtight seal, just like a factory fit. These keep the injectors located in the center of the manifold's injector bore and keep them from pushing into the manifold. One set contains 4 aluminum adapters. These adapters are also available specifically for the H22 Euro-R manifold and we also offer a shorter version for using RDX injectors in an H series manifold.
Adapters are 21mm OD x 13mm tall
