The product is a set of OEM ignition coils designed for 2011-2017 Ford and Lincoln vehicles, specifically for the EcoBoost and Flex models. The ignition coils are manufactured by the OEM supplier and have a front placement on the vehicle. The part number for this product is BL3E-12A375-CC, and it is compatible with a specific year and make of vehicles. This set includes the necessary components to ensure efficient ignition performance for the specified vehicle models. I got these ignition coils from my 2017 Ford expedition they were purchased from a salvage yard. I never even use them because it ended up being a different problem.
