Yep, talkin bout the cheapies. The tr55ix's are iridium, the tr55's are copper, hence the price difference. I ran some Denso iridiums for a while, and it ran exactly the same as it does with the tr55's as far as I can tell. Iridium plugs will last much longer, which is great if you're don't wanna spend alot of time working on your vehicle...

TR6's here too and my truck feels just as good as it did with the stock plugs when I am on motor....... which is kind of surprising because I thought that it would maybe be a little sluggish because they are a colder plug.
