Overview Haltech's Pressure Sensor Extension Kit delivers the cable length you need to properly route pressure sensors in complex engine builds. At 450mm (18"), this extension eliminates the compromises of short factory leads, allowing proper sensor placement away from heat sources whilst maintaining signal integrity throughout your EFI system. Technical Specifications Part Number: HT-039103 Extension Length: 450mm (18") Cable Type: Shielded automotive grade Connector Type: Haltech pressure sensor compatible Operating Temperature: -40°C to +125°C Why You Need This Engine bay packaging often forces pressure sensors into compromised locations — too close to exhaust manifolds, turbos, or buried where they're impossible to service. This is particularly problematic on LS swaps into tight chassis, RB builds with front-mount intercoolers, or any turbo setup where the factory sensor position puts it directly in the heat path. Poor sensor placement leads to heat-soaked readings, premature sensor failure, and tuning headaches. The 450mm extension gives you the freedom to mount MAP sensors, boost reference sensors, and other pressure monitoring devices where they belong — away from extreme temperatures, accessible for maintenance, and properly secured. We've used these extensively on SR20 builds where the standard sensor position conflicts with aftermarket intake manifolds, and on 2JZ turbo conversions where relocating the MAP sensor away from the hot side improves reliability significantly. The shielded construction maintains clean signals even when routed near ignition components or high-current wiring. ECU & System Compatibility Compatible with all Haltech pressure sensors across the Elite 550, Elite 750, Elite 1000, Elite 1500, Elite 2000, Elite 2500, Nexus R3, Nexus R5, and Platinum series ECUs. Also works with WB1 and WB2 wideband controllers requiring pressure references. Contact our technical team to confirm compatibility with your specific sensor and ECU combination.
