    Need help with fuel injectors ASAP

    Just purchased a set of 42 lb/hr D4 High-Z Fuel Injector MT SB. They showed up and I noticed they are half the size of my stock ones. My question is, can I buy an extension kit or am I sol? The kits I can get are: 16.1mm kit or a 4.6mm kit. They are also available in BARE, whatever that means. Thanks in advance.
