Understanding your vehicle's Spark plugs and the importance of its maintenance

Spark plugs ignite the air/fuel mixture in your engine's combustion chambers to power your vehicle. Over time, spark plugs wear and can develop carbon buildups decreasing their effectiveness, resulting in poor fuel economy and engine performance. Inspect and replace your vehicle's spark plugs at the required intervals.
*For complete maintenance information, please refer to your Vehicle's Owner's Manual or Service Maintenance Guide, or contact your retailer.
