Caution: Clean the spark plug recess area before removing the spark plug. Failure to do so could result in engine damage because of dirt or
foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper
seating of the new plug. Use a thread chaser to clean the threads of any contamination.
2. Use compressed air in order to remove debris from the spark plug cavity.
Caution: Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug
threads to seize, causing damage to cylinder head threads.
