HKS Pressure Sensor Kit 2013-2025 BRZ / FRS / 86 | Super Wide-Range Accuracy | Performance Sensor Upgrade
Overview
The HKS Pressure Sensor Kit is a precision-engineered upgrade designed specifically for the FA20 and FA24 engines found in the 2013-2025 Subaru BRZ, Toyota 86, and Scion FR-S platforms. This kit replaces the factory pressure sensor, which is limited in its ability to accurately measure boost pressure in forced induction setups. It is ideal for enthusiasts running turbochargers, superchargers, or high-boost naturally aspirated configurations who require reliable and accurate pressure data for tuning and performance monitoring.
Developed with a focus on durability and precision, the HKS sensor features a super wide-range measurement capability up to 294 kPa (3 kg/cm²), far exceeding the stock sensor’s range. Manufactured in Japan, the kit includes a dedicated mounting bracket and harness for a clean, OEM-quality installation. It also provides a port for an additional boost gauge connection, allowing drivers to monitor boost pressure in real time without interfering with the ECU sensor signal.
For Subaru and Toyota owners, this sensor upgrade means more accurate boost readings, which are critical for safe and effective engine management under forced induction. The kit is compatible with OEM and HKS Dry Carbon Engine Covers without modification, maintaining the clean engine bay aesthetics Subaru enthusiasts expect. Proper ECU calibration is required to fully utilize the sensor’s capabilities, ensuring optimal performance and reliability on both street and track applications.

Installation & Compatibility
Installation of the HKS Pressure Sensor Kit requires moderate mechanical skill and basic tools. The kit is designed for direct replacement of the factory sensor with included bracket and harness for a clean installation. However, ECU pressure sensor parameter adjustments are mandatory to ensure accurate readings and proper engine management. For FA20 engines with the black intake manifold, minor modifications to the intake manifold are necessary; no modifications are required for red manifold FA20 engines or FA24 engines. Professional tuning or flashing of the ECU is strongly recommended to recalibrate the pressure sensor offset and voltage slope.
-
Professional Installation: Recommended for ECU calibration and manifold modification if applicable
-
Modifications Required: Minor modification for FA20 black intake manifold; none for red manifold or FA24
-
Verify Compatibility: Confirm fitment for your specific year and intake manifold type before purchase
