Which Spark Plugs in a 2016 Lincoln MKT 3.5L in Flex & Lincoln MKT Forum Posted January 9, 2021 Motorcraft SP-534? 542? 580? Something else? Does anyone know the difference between these? Only performance mods are Air Raid CAI, TRQ Ignition Coils ICA64254 For best performance (without ruining the engine) what gap can I do? .030? .031? .028?
