Injector Extension Cups for 14mm Fuel Injectors

Description

Injector Adapter Extension Cups for 14mm Injectors (Shorty Injector Extension)

These Injector Adapter Extension Cups are designed to let you run 14mm “shorty” fuel injectors in applications where the injector needs extra length to properly seat between the fuel rail and the intake manifold. They act as a precision spacer/adapter, helping correct injector height so the injector sits correctly and seals as intended.

What These Do

• Extends short injectors to better match rail-to-manifold spacing
• Helps achieve proper injector positioning in the fuel rail and manifold
• Designed around 14mm injector sizing (common across many performance injectors)
• Ideal for builds mixing and matching fuel rail + manifold combos

Fitment Notes

• Universal fitment — not limited to VW/Audi specific setups
• Commonly used when adapting short-body injectors to setups originally sized for longer injectors
• Verify your measurements before purchase: rail height, manifold depth, injector length, and seal style vary by application

Great For

• Turbo builds and engine swaps using aftermarket shorty injectors
• Custom fuel system setups needing injector height correction
• Solving injector “too short” fitment issues without changing your rail or manifold

Important

These are intended to assist with injector fitment and positioning. Final sealing depends on your injector O-rings/seals and the condition of your fuel rail/manifold seats. Always pressure-test your fuel system after installation.
