Additional fuel injector holder / boss, CNC machined from billet 6061 aluminum.

  This weld-on fuel injector bung is used mainly in forced induction applications, welded to the charge pipe before throttle body in most cases.
   With more vehicles using Methanol and E-85 fuels, these have become a popular way to get more fuel in your engine without the cost of huge primaries. It also allows you to spray near or at the turbo compressor.


  • Fits Bosch EV-1, EV-6, EV-14 (standard and long length only), Siemens Deka and now the Billet Atomizer injectors!   
  • Select injector o-ring to o-ring length or style when ordering
  • Will only work with 14mm injector O-rings

  • CNC machined to fit precisely and weld on a 3″ diameter pipe.
