Spark plugs provide a mirror into the engine and can be used to diagnose problems. The spark plug shows the state inside the combustion chambers of the motor. The primary duty of the spark plug is to ignite the air-fuel mixture within the combustion chamber under any operating situation. The competent tuner can use spark plugs to identify the source of problems, determine air-fuel ratios, and improve vehicle performance.BR9ES SPARK PLUG (4/Pack) (86-5722) replaces WR3CC OE091 RN2C W27ESR-U.
