PLEASE CONTACT US IF YOU HAVE AN AFTERMARKET INTAKE!

The Bosch Design lll fuel injectors are .125 to .25 inch shorter than the stock TPi injectors. To solve all fitment issues we designed an adapter that fits onto the bottom of the injector. They are now the same length o-ring to o-ring as the stock TPi injectors. No modifying or milling necessary. Just "Plug n Play". INSTALL INJECTORS INTO INTAKE MANIFOLD FIRST, THEN THE FUEL RAIL FOR PROPER INSTALLATION & FITMENT !!!!!! These adapters are exclusive to SouthBay Fuel Injectors.
