am goin to replace my 6 spark plugs and leads, is it worth spending that lil extra and gettin the platnuim for all 6 or just puttin 6 iridums? goin to use champion leads.my mate gives me a wicked discount at a auto parts store so there is'nt that much difference in price ($10NZD)

what have u guys done?

Odd question - the Iridiums are stronger than Platinums; the electrodes are smaller, yet they should last longer and give a stronger spark. I've got the Iridiums and they work a treat !!!!!
