Which ignition coil set a 2014–2018 Silverado takes

Coils and plugs are specific to the engine, and the plug's heat range and gap are set by it. The 2014–2018 Chevrolet Silverado came with several powertrains, among them 4.3L V6 Automatic RWD, 5.3L V8 Automatic 4WD and 6.2L V8 Automatic 4WD. That is why we ask for the VIN, or the year, engine and trim, and confirm the part against it before you pay rather than after it arrives.
