The MODE Auto Concepts fuel-it-flex-fuel-kits-ford-mustang-5-0 is a flex fuel kit engineered for 2015-2023 Ford Mustang GT models with the 5.0L Coyote engine. This system provides crucial real-time ethanol content monitoring through a Bluetooth connection, allowing you to view the precise E-content via the Fuel-It! or JB4 mobile application. This eliminates the guesswork associated with E85 pump variations, which can range from E50 to E85 or higher seasonally. The kit boasts plug-and-play fuel line integration and utilizes ethanol-safe PTFE fuel lines and fittings. Installation is straightforward, typically taking approximately 30 minutes, with no cutting or permanent modification required. The system is compatible with both manual and automatic transmission models. This flex fuel kit is essential for those running E85 or ethanol blends in their 5.0 Mustang. It enables precise E85 blend management at every fill-up, helps avoid running too much ethanol on a pump gas map, and allows for safe maximization of timing and boost on ethanol maps. By providing accurate fuel mixture data, it helps maintain consistent performance and protect your engine from unknown fuel compositions. The kit is available with nylon or custom billet fittings, with the latter offering enhanced durability and aesthetics. A crimping tool option is also available for certain model years (2018+ do not require a crimp tool).
