Spark plugs are essential to engine performance - they produce the electrical spark that ignites the air-fuel mixture in the combustion chamber. A properly specified and well-maintained spark plug helps sustain efficient combustion, optimize fuel economy, and prevent rough idling or misfires. Worn or incorrect plugs can lead to power loss, higher emissions, and reduced drivability.

Manufactured by BERU, a trusted supplier of ignition technology, this spark plug is built with precise heat range and electrode design suited to the Boxster’s engine requirements. Its durable construction resists fouling and wear, delivering consistent spark performance under daily driving and spirited conditions alike. Supplied as an individual unit, you can order the exact quantity needed for maintenance or service.

•  Generates a controlled spark to ignite the air-fuel mixture
•  Supports smooth combustion, steady idle, and responsive performance
•  Helps maintain fuel efficiency and reliable starting

Spark plugs are vital to reliable ignition and efficient combustion. As they wear, spark quality deteriorates, which can lead to misfires, rough running, reduced performance, and increased fuel consumption. Replacing spark plugs at the correct interval helps maintain smooth engine operation, protects the ignition system, and ensures consistent drivability.

When spark plugs should be replaced:
•  At the manufacturer’s recommended service interval
•  If the engine misfires or runs unevenly
•  When cold starting becomes difficult
•  If fuel economy or throttle response declines
•  When plugs show signs of wear, fouling, or corrosion
•  During major servicing or preventative maintenance
