Spark plugs are essential components of the ignition system, producing the electrical spark that ignites the air–fuel mixture inside each combustion chamber. Using correctly specified spark plugs helps maintain efficient combustion, smooth idle, crisp throttle response, reliable cold starting, and optimal fuel efficiency. Over time, spark plugs wear or become fouled, which can cause misfires, rough running, reduced power, and higher fuel consumption if not replaced at the proper interval.
Manufactured by BERU, a trusted supplier of ignition technology, these spark plugs are built with precise heat range and electrode design matched to the Porsche Boxster 986 2.5L. The durable construction resists fouling and wear, delivering consistent ignition performance and long service life under both everyday driving and spirited use.
