Brisk racing makes a neat line of spark plugs using a silver center electrode which has the advantage of acting like a fuse in the event of high combustion temperatures that might otherwise melt a cylinder down. in this circumstance the silver electrode melts away and blows harmlessly out the exhaust valve as liquid silver which causes the cylinder to misfire instead of potentially melting down into a pile of sadness.

the DR14YS is a direct fit for the AAN engine, #14 heat range which is equivalent to bosch #5. in other words, moderately cold and good for high horsepower engines where we would normally fit the fr5dtc tri copper bosch plugs. gap to .020".
