OE Match spark plug for Porsche - direct replacement for part 99917019590, engineered to deliver reliable ignition performance, consistent combustion, and proper fuel burn with OE-equivalent fit and function.

The spark plug provides a controlled electrical spark inside the combustion chamber to ignite the air-fuel mixture. This ignition process is essential for engine power, efficiency, and smooth running.

Function:
•  Produces the ignition spark for combustion
•  Supports smooth idle and throttle response
•  Helps maintain proper engine efficiency and fuel burn
•  Designed to match OE Porsche performance and heat range.

A deteriorated or worn spark plug can cause misfires, rough running, sluggish acceleration, and lower fuel efficiency. Replacing with an OE Match spark plug ensures ignition performance that closely mirrors the original specification, helping maintain engine health and reliable operation.

When to replace:
• Rough or unstable idle
• Hesitation or lack of power under acceleration
• Poor fuel economy
• Misfire codes or engine warning signs
•  At regular maintenance intervals or during tune-ups
