Air Temp Sensor - 1/8 NPT Thread

Overview

Essential air temperature monitoring for any serious EFI build, this precision Haltech air temp sensor delivers accurate intake charge temperature readings that your ECU needs for proper fuel and ignition mapping. Whether you're running a turbo setup that needs intercooler monitoring or an NA build requiring ambient air compensation, this 1/8 NPT threaded sensor integrates seamlessly into intake manifolds, intercooler pipework, or airbox installations.

Technical Specifications

• Part Number: HT-010206
• Thread: 1/8 NPT
• Sensor Type: NTC thermistor
• Temperature Range: -40°C to +150°C
• Response Time: Fast thermal response for real-time monitoring

Why You Need This

Air temperature directly affects air density, and your ECU needs accurate readings to calculate proper fuel delivery and ignition timing. Without proper air temp compensation, you're leaving power on the table in cold conditions and risking lean-out in hot weather. This becomes critical in forced induction applications where intercooler efficiency varies dramatically with ambient conditions and boost levels. We see too many builds running generic sensors that drift or fail under heat cycling, causing erratic fuelling and potentially costly engine damage.

The compact 1/8 NPT thread makes this sensor perfect for tight installations in SR20, RB, and 2JZ intake manifolds where space is premium. Popular mounting points include pre-turbo intake pipes for ambient monitoring, post-intercooler for charge temp measurement, or directly in the plenum for true intake air temperature. The threaded design eliminates the reliability issues of push-in sensors that can work loose under vibration or boost pressure cycling.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range including Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 ECUs. The sensor connects directly to any available analog temperature input and calibrates automatically when selected in NSP software. Works equally well with Platinum series ECUs for older builds requiring air temp compensation.
