An "engine plug service" refers to the maintenance procedure of inspecting, cleaning, and potentially replacing the spark plugs in an engine, which are responsible for igniting the air-fuel mixture within the combustion chamber, allowing the engine to run properly; this typically involves removing the existing spark plugs, visually checking them for wear and damage, cleaning if necessary, and replacing them with new ones if they are beyond their lifespan or show signs of malfunction.
Key points about an engine plug service:
What it includes:
Removing spark plugs, inspecting for signs of wear like electrode erosion, carbon buildup, cracked porcelain, checking the spark plug gap, cleaning if possible, and replacing with new spark plugs if needed.
Why it's important:
Worn spark plugs can lead to poor engine performance, decreased fuel efficiency, rough idling, difficulty starting, and potential misfires.
When to get it done:
Consult your vehicle's owner's manual for the recommended replacement interval, but typically this service is performed as part of a routine tune-up every 30,000 to 100,000 miles depending on your vehicle and driving conditions.
