Volvo Engine Ignition Coil 30713417, direct replacement for original factory power stability

When your Volvo engine shows idle instability, acceleration jerks, or engine fault light is on, aging ignition coil causing insufficient ignition energy is likely. This part converts low voltage to high voltage to precisely drive spark plug ignition, ensuring smooth power output. OEM number 30713417 (compatible with 307134170, 307134171); fits multiple Volvo models with five-cylinder engines. Installation requires disconnecting the battery negative terminal and ensuring the ignition coil and spark plug contact surfaces are clean; tighten bolts to factory torque to avoid secondary faults from poor contact.
