This replacement uses OEM-consistent epoxy encapsulation; copper winding density is about 12% higher than CM5G12029FA, with tested thermal cycling over 3000 cycles, stable life. OEM CM5G12029FB, perfectly replacing CM5G12029FA and CM5G12029FC, fits Ford Focus, Escape and other models with 1.5T EcoBoost engine. Function: converts 12V low voltage to high-voltage pulses to drive spark plugs, directly impacting idle stability and acceleration response. Install as direct replacement by unplugging original coil and removing mounting bolts; cold-start operation recommended, clean carbon around spark plug holes to prevent debris entering cylinders.
