Pressure Sensor Extension Kit Length: 450mm (18″)

Vibration Isolation Management: Pressure Sensor Extension Kit (450mm)

In high-performance engine building, the longevity of a sensor is often determined by its environment. High-frequency vibration and intense thermal cycles are the primary destroyers of precision pressure transducers. The Pressure Sensor Extension Kit, featuring a 450mm (18″) Fragola -4 AN hose, is the professional engineering solution for protecting your electronics. Designed to suit 1/8th NPT MAP, Oil, and Fuel Pressure sensors, this kit allows the builder to remote-mount sensitive sensors away from the engine block or fuel rail, ensuring your standalone ECU integration receives a clean, stable signal for accurate fuel map calibration.

Engineering Principles: Harmonic Damping and Signal Stability

Motorsport pressure sensors, specifically the Haltech Motorsport and “TI” series, use delicate silicon sensing elements that can fracture when subjected to the harsh harmonics of a high-RPM engine. The Fragola -4 AN Hose included in this kit acts as a high-frequency dampener, isolating the sensor from mechanical shock while still providing a direct fluid/air path for pressure measurement. This is foundational for harness integration in professional racing; by remote-mounting the sensor on the firewall or a dedicated bracket, you drastically reduce EMI and signal “jitter,” which is critical for maintaining accurate detonation protection maps that rely on stable fuel or oil pressure data.

Operational Benefits: Accessibility and Hardware Longevity

One of the primary Notes for Haltech pressure sensors is that they must not be mounted directly into the fuel rail or engine block. This extension kit provides the necessary hardware to comply with this requirement. By moving the sensors to a more accessible location, diagnostic work becomes significantly easier during track-side service. For turbocharged 2JZ or LS-swap builds, remote-mounting pressure sensors also keeps them away from the extreme radiant heat of the turbocharger, preventing thermal drift in the Analogue-to-Digital interface. The kit is supplied with rubber-insulated P-clamps to ensure the hose and sensor are secured without creating new vibration points.

Fitment and Integration Strategy

This extension kit is a universal solution compatible with any 1/8 NPT pressure sensor. The kit includes the high-quality Fragola braided hose, male and female 1/8th NPT adaptors, and insulated P-clamps for a motorsport-standard finish. During installation, the male adaptor connects to the engine/rail source, and the sensor threads into the female adaptor on the other end. This setup provides the tuner with a deterministic pressure signal that can be used for closed-loop boost control or fuel pressure safety strategies. It is a mandatory addition for any build using Haltech’s range of motorsport pressure transducers.
