Haltech HT-010204 Air Temp Sensor 1/4 NPT Nissan Z32 300ZX Intake Delphi Plug

Vehicle Fitment

• 1990-1996 Nissan 300ZX (Z32, VG30DETT / VG30DE, RWD) - direct fit for OEM intake manifold thread boss
• Universal - also fits any intake manifold, throttle body, or custom piping with a 1/4 NPT thread boss

Fitment Notes

• Thread size is 1/4 NPT - specifically sized to fit the Nissan Z32 300ZX intake manifold air temperature sensor location without modification.
• Also compatible with any custom or aftermarket intake setup using a 1/4 NPT weld-in or machined thread boss.
• Maximum operating temperature is 127°C (260°F). Do not install in locations exposed to temperatures exceeding this limit.
• Sensor type is NTC thermistor - directly compatible with standard Haltech analog temperature input calibrations in all Haltech ECU software.
• Includes matching Delphi plug and pins - no separate connector purchase required.

Features

• Measures intake air temperature (IAT) and delivers real-time data to the ECU for accurate fuel and ignition mapping.
• 1/4 NPT thread - correct size for the Nissan Z32 300ZX OEM intake manifold sensor port, enabling a direct, leak-free installation.
• Built to OEM specifications for reliable, consistent output across the full operating temperature range.
• NTC thermistor sensor type - directly compatible with all Haltech ECU analog temperature input calibrations.
• Weatherproof Delphi connector ensures a secure, moisture-resistant connection in demanding engine bay environments.
• Matching Delphi plug and pins included - ready to wire without sourcing additional connectors.
• Suitable for all Haltech ECU platforms including the Nexus S2, S3, R3, R5, and Elite 550 through 2500 series.
• Essential for accurate air density compensation on both naturally aspirated and turbocharged builds.

Product Description

The Haltech HT-010204 is a 1/4 NPT air temperature sensor designed specifically to fit the Nissan Z32 300ZX intake manifold's OEM sensor port, making it the go-to choice for Z32 EFI conversion and standalone ECU swap builds. The 1/4 NPT thread provides a direct, leak-free fit in the factory boss without the need for adapters or modification. Beyond the Z32, the sensor is equally at home in any custom intake fabrication or aftermarket manifold machined with a 1/4 NPT thread boss.

Like all Haltech air temperature sensors, the HT-010204 is built to OEM specifications using an NTC thermistor element, providing accurate real-time intake air temperature data to the ECU for fuel and ignition correction across varying conditions. The included Delphi plug and pins make wiring straightforward, and the sensor is natively calibrated in all Haltech ECU software. With a 127°C (260°F) maximum operating temperature, it is best placed in the intake manifold or intercooler outlet piping well upstream of the throttle body.
