Spark plugs are a critical part of the ignition system, producing the spark that ignites the air-fuel mixture within each cylinder. Correct ignition timing and a strong, consistent spark are essential for smooth engine operation, optimum fuel economy, responsive acceleration, and reduced exhaust emissions. As spark plugs wear, ignition efficiency gradually declines, which can lead to rough idling, reduced performance, increased fuel consumption, and engine misfires.

Why Replacing Spark Plugs Matters
Spark plugs naturally wear over time, reducing the strength and consistency of the ignition spark. Replacing them at the recommended service interval helps restore engine performance, improve fuel efficiency, reduce emissions, and ensure reliable starting in all driving conditions.
When to Replace Spark Plugs
• At the manufacturer's recommended service interval
• If the engine misfires or idles roughly
• Poor fuel economy
• Difficult starting or hesitation under acceleration
• Reduced engine performance
• During a scheduled ignition system service
