Spark plugs are essential components of the ignition system, responsible for generating the electrical spark that ignites the air-fuel mixture within the combustion chamber. Correct specification spark plugs help maintain smooth idle, reliable cold starts, responsive throttle performance, efficient fuel combustion, and controlled emissions. Over time, spark plugs wear or become fouled, which can lead to misfires, reduced engine power, rough running, or increased fuel consumption.
Manufactured by Bosch, a world-renowned original equipment supplier to Porsche, these spark plugs are engineered to OEM specifications with the proper heat range and electrode design required by modern flat-six engines. Durable construction and precise manufacturing help deliver stable ignition performance, long service life, and dependable operation under both daily and spirited driving conditions. Ideal for routine servicing, preventative maintenance, or restoring peak performance.
