Flex Fuel Upgrade for NexGen Stage 2 Kit

The COBB Flex Fuel Upgrade for NexGen Stage 2 Kit is an essential addition for Subaru WRX STI owners who have already installed the Cobb NexGen Stage 2 Power Package. This upgrade integrates Cobb's NexGen Ethanol Content Sensor Kit and Fuel Pressure Sensor Kit, enabling your vehicle to safely utilize higher ethanol content fuels, such as E85, found at many fueling stations. By incorporating these sensors, the Flex Fuel Upgrade allows your NexGen Stage 2 Power Package to take full advantage of the performance benefits offered by E85. This is crucial for optimizing engine performance, especially when paired with the specific NexGen Stage 2+FlexFuel Off The Shelf (OTS) maps provided by COBB. It is important to note that this is not a standalone flex fuel kit. It requires the complete hardware from the Cobb NexGen Stage 2 Power Package to function correctly. The kit is designed for all Subaru 2008-2021 Subaru WRX STI models that are already equipped with the Cobb NexGen Stage 2 Power Package.
