SPARK PLUGS & IGNITION SYSTEM MAINTENANCE

Though many spark plugs are designed to last up to 80,000 – 100,000 kilometers, they can still get dirty or fail prematurely. Ignition wires lose insulating ability over time, and the connection to the plug or ignition coil can degrade as well. Having your service technician or independent workshop regularly inspect your ignition system can help you avoid conditions that may result in poor performance or reduced fuel economy.
