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. These are original Porsche specification spark plugs for the following vehicle application :- Porsche 944 2.5L (8 valve) & 2.7L models (1982-1989) Porsche 944 Turbo 2.5L (8 valve) (1986-1991) Porsche 924S 2.5L (1985-1988)
