Product Support and Information

Spark plugs are a critical component in petrol and hybrid engines, providing the electrical spark needed to ignite the air–fuel mixture inside the combustion chamber. Correct spark plug performance ensures efficient combustion, smooth engine operation, optimal fuel economy, and reduced emissions.

Why Do They Fail?

Spark plugs operate under constant heat, pressure, and electrical load. Over time, wear and contamination reduce their ability to produce a strong, consistent spark.

Common causes of failure include:

  • Natural electrode wear over time

  • Carbon fouling from incomplete combustion

  • Oil contamination from worn engine components

  • Incorrect heat range or specification

  • Extended service intervals or poor-quality fuel

Symptoms of a Failed Spark Plug

A failing spark plug can quickly affect engine performance and drivability.

Typical symptoms include:

  • Engine misfires or hesitation

  • Rough idle or poor acceleration

  • Increased fuel consumption

  • Difficulty starting the engine

  • Engine management warning light or misfire fault codes

Left unchecked, faulty spark plugs can place additional strain on ignition coils and catalytic converters.

Fitting Tips

Correct installation is essential to ensure spark plug performance and longevity.

Best practice fitting tips:

  • Always check the correct specification and heat range

  • Replace spark plugs as a complete set where possible

  • Check and set electrode gap if applicable

  • Install using the correct torque setting

  • Avoid overtightening to prevent thread or insulator damage

✔ Professional installation is recommended
✔ Always follow vehicle manufacturer service intervals
