Ford Ignition Coil E3BG-12A366-BB Replaces Original Factory Ignition Coil

Ford ignition coil E3BG-12A366-BB mounted on top of the engine cylinder head, directly connected to the spark plug, responsible for converting low voltage to high voltage to ignite the air-fuel mixture. OEM number E3BG-12A366-BB, fits multiple 4-cylinder models such as Focus and Kuga. Installation difficulty is moderate; estimated labor time about 1 hour; must remove in order and avoid damaging the seal. If the vehicle exhibits acceleration hesitation, rough idle, hard starting, or a check engine light, this typically indicates coil aging or breakdown and should be replaced promptly to protect ignition efficiency and fuel economy.
