I wouldn't use Bosch and wouldn't touch Denso if they were the last plugs on the planet.

What make was the plug that melted on your last engine?
It didn't melt, a lump of ceramic broke off causing damage to piston, head and bore on number 2...I forgot make but son says it was Denso....this was when Iridium plugs were new, there was a number of cases of this failure recorded. When my son took his Modified RS turbo for a tune of the dyno after he built the engine they wouldn't run the car with Iridium plugs because of these failures...His RS still made 325bhp though...
