Show original supplier description
This kit includes a custom, easy-to-install, plug-and-play wiring harness that utilizes OE quality connectors for a reliable connection. This NexGen Flex Fuel Module allows for real-time ethanol percentage and temperature monitoring, which is crucial for vehicles running flex-fuel or E85 blends. The data can be utilized with Cobb's Accessport for advanced tuning and performance optimization. The Cobb COBB325650 is explicitly listed as fitting Subaru STI models from 2008 to 2021, including the 2018 Type RA. The product is also noted as being universally compatible, but it is always recommended to verify fitment for your specific vehicle configuration.
