Honda Fit Ignition Coil 30521RBJ003 / 30521RBJS01 / CM11118 Original Equipment Parameter Matching

When your Honda Fit experiences acceleration hesitation, rough idle, check engine light, or even cold-start difficulty, the ignition coil may be aging or failed, resulting in insufficient ignition energy. This part converts low voltage to high voltage to reliably ignite the air-fuel mixture. OEM number: 30521RBJ003, also compatible with 30521RBJS01 and CM11118, for Honda Fit 1.5L 4-cylinder engines. Install with factory-specified screws and torque; ensure contact surface between ignition coil and spark plug is clean and oil-free to avoid secondary failure from poor contact.
