Mazda Series Ignition Coil B61P1810XD Replaces B61P1810XB/C High Efficiency Ignition

When Mazda vehicles show rough idle, weak acceleration, rising fuel consumption, or engine warning lamp on, ignition coil aging likely causing insufficient ignition energy or intermittent misfire. This part, under normal operation, converts low voltage to high voltage to ignite the air-fuel mixture in the cylinders, ensuring smooth engine operation and power output. OEM number B61P1810XD; replaceable for B61P1810XB/C; suitable for Mazda3, Mazda6, CX-5 with 4-cylinder engines. Installation requires disconnecting battery negative and checking spark plug condition; simultaneous replacement recommended to ensure ignition system compatibility.
