Porsche 996 Carrera 3.6L & Boxster S 3.2L (987) spark plugs
Having the correctly specified spark plug in your Porsche engine ensures that your spark plug always operates at it's optimum temperature & ignition voltage. Any deviation from this leads to reduced spark plug durability, reduced spark energy, a poor spark, poor ignition and misfires. Any single misfire will directly effect the overall emissions of your vehicle, damage the catalyst and can illuminate your engine warning lamp.
