Height Adapter 1/2" (14mm O-Ring)

Awesome customer service

Great project, fast shipping, and someone picks up the phone when you call.

Awesome support and product

Installed a FAST Intake on my LS3 using OEM fuel rail. I wanted the adapters that go on top of the injector instead of the bottom, which could potentially affect spray pattern. Called FIC to confirm fitment, and they were awesome in confirming part for my setup. They are installed and working perfectly.

These are the ONLY adapters to buy

I bought adapters for most every supplier and the fuel injector business. These adapters are hands-down, the most consistent and quality, the best fit, and the shipping time can’t be beat. Save yourself the frustration and buy these adapters!
