Product Description:

Bosch WR5DC spark plug
Bosch Discontinued the original W5DC spark plug in 10/2007. Bosch has replaced almost all of their copper electrode spark plugs with resistor style plugs. Resistor style spark plugs are required when using DME, (digital Fuel injection), because the electrical impulses from the ignition system can and will interfere with the sensors used on most electronically fuel injected engines.
The total system resistance used on factory Porsche vehicles that use a CDI ignition are tuned to give the optimum amount of spark energy to the plug. Now yes you can use a resistor spark plug with a CDI system but our research has shown that the location of the resistance and the total amount of the resistance per spark plug is key to getting the best out of the CDI.
We would recommend using this plug in a high compression electronically fuel injected engine that is running a TCI or other type of inductive ignition system, where you require a spark plug with a "5" heat range
