Keeping an eye on your fuel pressure can help ensure a healthy running engine. This is especially true on an engine requiring more fuel for the power levels above factory ones. Potential dips in fuel pressure as demand increases on your Subaru WRX STI can lower performance and even damage your engine. Each COBB fuel pressure monitoring kit includes a plug and play harness, fuel pressure sensor, and a billet aluminum sensor adapter. Each kit can be easily installed with minimal work. The kit does require a COBB AccessPORT to tune and use as a display for the pressure sensor gauge.

Key Features:

• Kits are direct fit to each application.
• Uses COBB AccessPORT as a display for the sensor.
• Aluminum 1/8" NPT adapters.
• Custom plug and play harnesses for each application.
• 0-100 PSI sensor (higher on some applications).
• All hardware needed to install is included.
• Required for COBB NexGen Flex Fuel OTS Maps.

Fuel Pressure Kit Notes: The COBB AccessPORT is used as both the tuner and gauge for these kits, and thus is required for proper operation.
