Reply to "Spark plug recommendation"

George PAdmin.

Fredrik,

platinum plugs are installed by the OEM's in order to extend service life. The ignition does not care what material the spark plug electrodes are made of. In the US auto manufacturers are required by the federal government to warrantee the emissions systems for 100,000 miles. This has forced them to design spark plugs that will maintain optimum performance for 100,000 miles. This has resulted in the use of very small "pointed" platinum electrodes. The new Bosch "surface gap" style spark plugs with either 2 or 4 side electrodes looks like a good design as it completely "unshrowds" the spark.
