This package is intended to be added to the 50-state legal Cobb NexGen Stage 2 Power Package. It includes both Cobb's NexGen Ethanol Content Sensor Kit and Fuel Pressure Sensor Kit, required for use with the supporting NexGen Stage 2 FlexFuel Off The Shelf (OTS) maps.

This combination of their NexGen Ethanol Content Sensor and Fuel Pressure Sensor Kits allows users to take full advantage of their NexGen Stage 2 Power Package by adding the ability to take advantage of higher ethanol content fuels found at E85 fueling stations.

Note that this kit REQUIRES all the existing hardware from the Cobb NexGen Stage 2 Power Package. This is NOT a stand-alone flex fuel kit.

Fits all Subaru 2015-2021 Subaru WRX STI.
