Yeah, NGK would be nice but I want something that isn't going to be needed replaced in 30K or so... I was contemplating Nippondenso Iridium plugs.. But they're 15.00 a piece.. But they last a lifetime from what I am told. Almost 3 times stronger than platinum and can withstand almost double the heat... Oh well... I'll tinker with them when the price drops a little... Just don't let me find out that anyone here has installed Splitfire plugs in their Tour... shame on you, what a bad waste of money!
