About the Mantis MTP-1027 Focus RS Mk3 Performance Ignition Coils.
Stronger spark for the RS's 350PS 2.3 EcoBoost.
The Mk3 RS works its ignition system harder than almost anything else Ford builds - 350PS from 2.3 litres as standard, and most of them mapped well beyond that. Head-gasket-era engines, big-turbo builds and track cars all show the same first symptom when coils age: misfires under boost.
The Mantis MTP-1027 is a direct replacement engineered around a neodymium core delivering 12% more spark energy than standard OE coils - with the thermal headroom a hard-driven RS demands.
Signs your Focus RS needs new coils
