Motorcraft CYFS12F5 Finewire Platinum Tip Spark Plug

The Finewire Platinum spark plug was designed to improve electrode wear beyond the capability of the Single Platinum spark plug. The quantity of platinum is 2 to 3 times greater than the Single Platinum plug and its thin cylindrical shape serve to reduce the required firing voltage. This results in diminished erosion of the platinum and robustness against fouling.
