Why Replace This Part?
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 spark plugs as a complete set helps restore consistent ignition across the engine.

When to Replace This Part

•   Engine misfire, rough idle, or hesitation is present
•   Starting performance is poor
•   Fuel economy has reduced
•   Acceleration feels uneven or weak
