The spark plugs ignite the air and fuel mixture inside each combustion chamber. Correctly operating spark plugs help support smooth starting, stable idle, clean combustion, throttle response, fuel efficiency, and reliable engine performance.

Why Replace This Set?
Spark plugs wear over time due to heat, combustion pressure, electrode erosion, carbon build-up, and mileage. Worn spark plugs can cause misfires, rough idle, hesitation, poor starting, reduced performance, increased fuel consumption, or engine warning lights. Replacing all 6 spark plugs together helps restore consistent ignition across the engine.
When to Replace This Set
• Spark plug service interval is due
• Engine misfire, rough idle, or hesitation is present
• Starting performance is poor
• Fuel economy has reduced
• Acceleration feels uneven or weak
• Engine warning light or ignition fault codes are present
• Preventative maintenance is being carried out.
