Tell me about my Spark Plug Cable Replacement
Spark plug cables (also known as ignition leads) carry high-voltage electricity from the ignition coil to the spark plugs, ensuring the plugs fire correctly to ignite the fuel-air mixture. Over time, these cables can wear out, crack, or lose conductivity, leading to misfires, poor performance, and reduced fuel efficiency. Replacing faulty spark plug cables restores smooth engine operation.
What is a spark plug cable replacement?
This service involves removing the old or damaged ignition leads and installing new, manufacturer-approved cables. The mechanic will also check the spark plugs, ignition coil, and distributor (if fitted) to ensure the whole ignition system is working properly.
Why do you need a spark plug cable replacement?
Worn spark plug cables reduce the voltage reaching the spark plugs, causing weak or inconsistent sparks. This can lead to misfiring, rough idling, poor fuel economy, and engine hesitation. Replacing the cables ensures reliable ignition and smooth performance.

How much does a spark plug cable replacement cost?
Replacement typically costs $150–$350, depending on the vehicle and cable type. Costs may increase if spark plugs or coils also need replacing.
Is it unsafe to drive with faulty spark plug cables?
Yes. Driving with worn or damaged ignition leads can cause poor engine performance, stalling, and increased emissions. Long-term misfires can also damage the catalytic converter. Replacement should be carried out promptly.
