New Version direct fit for GM/TPi. With our modification to these injectors, the problem with them being shorter than stock is now solved! They now measure the same length o-ring to o-ring with the stock injector. No more milling, additional spacers or orings. Just “plug n play” for GM/TPi set ups.
