FAQ

  • How do I know if my spark plugs need replacing?

    Common signs include rough idling, poor acceleration, increased fuel use and hard starts. You might also notice your car misfiring or sounding off. If you're experiencing any of these, it’s worth having the plugs checked. We can test and confirm if a replacement is needed.

  • How often should spark plugs be replaced?

    It depends on the type of plug and your car's make and model. Most need replacing every 30,000 to 100,000 kilometres. We follow manufacturer guidelines and inspect the condition to know exactly when it’s time. Regular checks during servicing also help catch early signs of wear.

  • Can old spark plugs damage my engine?

    Yes, worn plugs can lead to poor combustion, reduced power and increased engine strain. Left too long, this can affect other components like coils and injectors. Replacing them on time keeps your engine running smoothly and avoids preventable issues down the track.
