I've read a few posts on plugs, some good info some bad, I've spoken to a few people in the know, seems there would be little noticeable difference between Platinum and Iridium plugs as they are both exceptional plugs, there is some great info on the NGK website, "NGK plugs Here" deffinately worth a read, click on the Irridium bit.. also seems that Irridiums are a little less expensive than Platinums, at Repco anyways, also helps having an account, (let me know if you want somein WA, I might be able to get a deal on a bulk lot) :thumbsup:
