When to know when a spark plug needs changing

Replacing your spark plugs is an important part of routine maintenance and servicing for your engine. Without a set of fully functioning spark plugs, you can notice running issues such as poor fuel economy, lack of acceleration or general performance, poor idle conditions, cylinder misfires, hard starting or even an engine that won't run at all. There may also be a build-up of carbon in the combustion chamber from unburnt fuel from not having the plugs spark.

Between replacement periods for your spark plugs, use a spark plug socket to remove the plug and perform a quick visual inspection. Examine for any oil or fuel deposits known as fouling on the tip of the plug which can hamper spark performance. You'll also want to look out for any damage to the spark plug threads and any cracks or other marks on the spark plug.

True surface gap spark plugs have no heat range. In comparison to regular spark plugs these are as cold a heat range as you can get.
