Description
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.

Fuel Injector Holder
Great deal good quality fit, function, finish CNC machined from billet 6061 aluminum. Can be welded anywhere in the intake manifold.

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.

Nice pieces
It’s great to get well thought out & fabricated pieces. Left enough material so I could machine them down for a perfect fit in a custom shovelhead manifold. Or could have been installed on an intake tube with no mods. Nice
