Spark Plug: Service and Repair

Crossthreading or failing to fully seat spark plugs can cause overheating of spark plugs, exhaust blow-by, or thread damage. Follow recommended torque specifications carefully. Over or under-tightening can also cause severe damage to cylinder head assemblies or spark plugs.
