No, it is not recommended to use silicone spray on spark plugs. Spark plugs require a clean, dry environment to function effectively. Silicone spray can act as a contaminant, potentially leading to ignition problems or misfires. Instead, use a small amount of anti-seize compound on the threads if recommended by the manufacturer, and apply dielectric grease only to the inside of the spark plug boot to ensure a good electrical connection.
