The other question (Q1) will be answered as you read on, Platinum and Iridium is used for it's hardness and resistance to wear, this gives longevity between service intervals, with Iridium being the harder of the two, PORSCHE 911 (997) V 911 CARRERA V COUPE (997) PHASE 1 2P 2004-07->2008-07 3.8i 381 F6 24V 4X4 (280kW) -M9701S- M6 An unaltered engine will run within the optimum operating range straight from the manufacturer, but if you make modifications such as a turbo, supercharger, increase compression, timing changes, use of alternate racing fuels, or sustained use of nitrous oxide, these can alter the plug tip temperature and may necessitate a colder plug. A rule of thumb is, one heat range colder per modification or one heat range colder for every 75–100hp you increase. In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70 degrees C to 100 degrees C from the combustion chamber!
