Weld Fitting M14 x 1.5 - Small Thread Air Temp Aluminum

Overview

Professional aluminium weld fitting designed for mounting small-thread air temperature sensors in custom intake manifolds, intercooler piping, and charge pipes. Essential for accurate IAT readings in turbo builds, EFI conversions, and performance applications where precise air temperature monitoring drives optimal fuelling and timing maps.

Why You Need This

Air temperature correction is critical in forced induction applications — every 10°C change in intake air temperature affects your air/fuel ratio by roughly 3%. Without proper IAT sensor placement, your ECU is making fuelling decisions based on ambient air temperature rather than actual charge air temperature, leading to knock, lean running, or overly rich mixtures that cost power and reliability.

This machined aluminium fitting provides the professional solution for integrating air temp sensors into custom intake systems. Whether you're building an LS turbo setup with a custom manifold, fabricating intercooler piping for an RB25 or SR20 build, or converting a classic to EFI, this fitting ensures your IAT sensor reads true charge air temperature. The M14 x 1.5 thread suits most small-body temperature sensors including Haltech's own units, and the aluminium construction provides excellent thermal conductivity for rapid sensor response.

ECU & System Compatibility

Compatible with all Haltech ECU systems requiring air temperature input — Elite 550, 750, 1000, 1500, 2000, and 2500 series, plus Nexus R3, R5, and Rebel units. Works with any aftermarket ECU accepting standard automotive temperature sensors with M14 x 1.5 small thread configuration.
