Cobb Subaru Fuel Pressure Sensor Kit (5 Pin) - 2015-2021 Subaru STI

The COBB Fuel Pressure Sensor Kit (5 Pin) is a plug-and-play solution that allows you to monitor fuel pressure directly through a custom Accessport monitor on supported Subaru STI applications. For cars running harder than stock—or relying on upgraded fuel system components—keeping an eye on fuel pressure is one of the smartest things you can do for both performance and peace of mind.

Using OEM-quality connectors and a billet aluminum sensor adapter, this kit delivers a clean, factory-like fit and finish while taking advantage of existing factory inputs for straightforward integration.

Why We Like It

Fuel pressure is one of those parameters you do not want to guess on—especially on a modified STI. This kit gives you a clean, reliable way to monitor a critical part of the fuel system, and it is especially important for cars running more aggressive calibrations or flex fuel setups.

Why Monitoring Fuel Pressure Matters

As the demand on your fuel system increases, so do the consequences of a failure or pressure drop. Monitoring fuel pressure can help alert you to faults before they become bigger problems, making this kit a smart supporting upgrade for tuned or fuel-system-dependent builds.
