The right Spark Plugs choice is about reliable combustion and ignition quality under load. Spark plug choice matters on tuned, hard-working or boosted engines where heat range, gap and service condition affect drivability.

Correct ignition hardware helps reduce misfires, rough running and performance inconsistency, especially when the engine is modified or worked hard.

Choose by exact engine, heat range, electrode type, plug gap, tune level, fuel quality, service interval and supplier recommendations for the setup.
