Our Tip
Timely Spark Plug Replacement Pays for Itself! Spark plugs are subject to wear and must be regularly replaced.
Otherwise there is a risk of incomplete combustion, increased fuel output and increased pollutant emissions as well as misfiring. Misfiring can result in unburned fuel reaching the catalytic converter. This can cause irreparable damage to the catalytic converter!
