Fuel Injector Adapter Spacer Short LS2 TO LS1 Intake or LS3 To Truck Intake This kit will allow you to run GM short LS2 injectors in a application where a LS1 injector height would normally be used. This kit will also allow you to run GM LS3 injectors or EV6/14/Denso (Not EV1) style Bosch 210 in a application where a GM Truck injector height would normally be used. These adapters use the factory injector clip and are made from 6061-T6 aircraft grade aluminum. They are CNC cut on a lathe for an incredibly precise fit and a leak free seal. We also include Viton oil/gas/solvent resistant o-rings for a long lasting seal. These spacers add approximately 0.40"-0.48" to each injector. The spacers get mounted on the top of the injector. If you were to put them on the bottom, the spray pattern of the injector would get messed up and the car would not run right.

Needed these to mix and match some harley injectors and throttle bodies for testing. worked great and have been installing them on customer bikes all year to update older altered injection systems.
