Rosko Racing Bosch EV14 style injector adapters are designed to fit the factory injector pockets of most B/D/H/F Honda intake manifolds. These adapters have a 14mm ID for proper injector fitment and a 21mm OD with an o-ring to secure and seal into a factory intake manifold. These adapters are 14mm tall and work in both shallow and deep Honda injector counter bores.
While these are meant to be a replacement part to the Rosko Racing fuel rail kits, they also work well fitting this style of injector into many different intake manifolds. Note however that the sole purpose of this adapter is to fit the injector into the manifold ONLY. You will most likely have to alter the installed height of the fuel rail with non Rosko Racing fuel rail applications. This means you may need to add or shorten the spacing of the fuel rail as adding this adapter will essentially make the injector taller. You will need to make sure the installed height of the rail is correct so that you do not damage your fuel injectors when installing.
Additionally, Rosko Racing also manufactures adapters specific for the H22 Euro-R intake manifold as well as a shorter adapter designed to work better with Acura RDX injectors.
Comes as a set of 4 adapters.
