Spark plugs play a critical role in engine performance by creating the electrical spark that ignites the air-fuel mixture inside the combustion chamber. Correct specification spark plugs ensure efficient combustion, smooth idling, crisp throttle response, reliable cold starting, and optimal fuel economy. Over time, spark plugs wear and can become fouled or eroded, leading to misfires, roughness, loss of power, and reduced efficiency.
Manufactured by Bosch, an original equipment supplier with a long-standing partnership with Porsche, these spark plugs feature durable construction and precise engineering for consistent ignition performance and long service life. Ideal for routine maintenance, preventive servicing, or restoring peak performance, this set of six ensures balanced combustion across all cylinders.

This OE Match iridium spark plug set (pack of 6) includes six identical plugs that closely emulate Porsche original equipment in thread dimensions, electrode design, and thermal characteristics, ensuring dependable combustion and longevity. These plugs are manufactured to meet OE-equivalent standards and are ideal for use in a range of Porsche models that require this spark plug reference.
PACK OF 6
Fits:
Each spark plug is built to be durable under repeated heat cycles and high combustion pressures typical of Porsche engines. The iridium-enhanced electrode construction (when applicable) delivers consistent sparks and improved wear resistance, supporting smooth idle quality, crisp throttle response, and efficient engine performance over time.
The set is a direct-fit replacement - no modification needed - and is perfect for routine maintenance, full ignition system refresh, or when worn plugs begin to degrade performance.
Spark plugs naturally wear with use. As they age, electrode gap increases, which can cause weak or inconsistent sparks, leading to misfires, rough idle, poor fuel economy, and loss of performance. Replacing all six plugs together ensures balanced ignition across all cylinders and helps preserve the health of ignition coils and catalytic components.
