Fuel Injector Adapter - 14mm Base

Overview

Transform your short 1/2 length (34mm) fuel injectors into full 3/4 length (48mm) units with this precision-machined 14mm adapter. Essential for achieving proper injector positioning and spray pattern when upgrading to high-flow injectors in manifolds designed for longer injectors. Eliminates fitment issues that plague modern EFI conversions and turbo builds.

Technical Specifications

• Base Diameter: 14mm with dual O-ring sealing
• Length Extension: Converts 34mm to 48mm injector length
• O-Ring Configuration: Top and bottom 14mm sealing rings
• Material: Precision-machined aluminium construction

Why You Need This

Injector length mismatch is one of the most common headaches in performance builds. Modern high-flow injectors often come in shorter 1/2 length format, but your intake manifold was designed for traditional 3/4 length units. Without proper positioning, you'll get poor fuel atomisation, uneven distribution between cylinders, and potential lean spots that destroy engines. This adapter solves the geometry problem completely.

We see this constantly on LS swap projects where customers upgrade to larger injectors but discover they sit too high in the manifold ports. The spray pattern ends up hitting port walls instead of entering the combustion chamber properly. Same issue affects RB25/26 builds, SR20 conversions, and classic Ford EFI upgrades. The 14mm base diameter suits most Japanese and European applications, while the dual O-ring design ensures leak-free sealing under boost pressure.

ECU & System Compatibility

Universal mechanical adapter compatible with all Haltech ECU systems including Elite 550/750/1000/1500/2000/2500, Nexus R3/R5, and Platinum series. The adapter works with any injector control system as it's purely a mechanical fitment solution. Your Haltech ECU will control the injectors normally once proper positioning is achieved.
