A friend of mine recently found NGK or Denso iridium sparks.These sparks are useful when the compression of your engine is higher than normal.For example if you change the Air/Fuel.If you haven't got such a problem then use the standard NGK sparks.

I need new spark plugs, mine have had their day. A friend has Iridium NGK ones in his Punto MK2 (and he reckons it makes a diff) . But I went to a few places and they looked up spark plugs for my car and Iridium ones weren't on the list for my car for NGK, just bog standard. So if I need new ones, might as well get the best.
