Spark plugs supply the electrical spark required to ignite the compressed air-fuel mixture inside your engine’s combustion chambers. Over thousands of miles, electrode erosion, high heat, and carbon deposits widen the spark plug gap, causing incomplete combustion. Worn spark plugs lead to engine misfires, rough idling, hesitation during acceleration, decreased fuel economy, and eventual catalytic converter damage. We test ignition performance and replace worn spark plugs and ignition coils with high-grade platinum or iridium components to ensure clean, efficient combustion.
