In Stock.  Ships within 1 business day.


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
  • Will NOT work with any short injectors (34mm). See our small holder for this application.
  • 1/4″ NPT thread for fuel fitting
  • 3/4″ flats to hold top while installing fitting
  • CNC machined to fit precisely and weld on a 3″ diameter pipe.
  • Straight end available upon request.
  • Spacers / dowels insure you are not tightening down on the injector body!
  • Stainless steel hardware

exactly what I needed...

I was making a customer a custom fuel injection system for his car and was having a tough time finding something to hold injectors individually and found these. The aluminum is quality and machines easy if needed. I milled the pieces to fit my application and it was perfect!

Excellent Product and Service

Cannot say enough positives. High quality product. We needed to make a change after ordering, and the response was fast and helpful. Will be back next time we have a custom fueling project. Thank you.

Injector mount!

A really nice piece for the price! I'm a machinist and I couldn't make that for the price you sell it for. I'm a forever customer.
