I sell the NGK's and MSD wires in a package deal for $75 delivered if anyone is interested. NGK TR55 or TR6 in stock as well as MSD 8.5 SUperconductor wires red or black.

I ship priorority which is 2-3 day so you will have them fairly quickly once you order. pm me to order and I'll take care of the rest.

I just installed the NGK iridums. Nothing to report, really. No noticable change in performance. Still getting the same gas mileage as I did with the stock platinums with 80k miles that I replaced. For unmodified engines, plugs don't affect the performance of our cars. It's just a matter if you want to pay the extra $ for irdiums knowing that you wont have to change them for 100k miles.

ngk tr55 = very good plugs
ngk tr55ix (the same thing, just iridium) = very good plugs that you don't have to change nearly as often.

Platinum is not worth it. It costs about the same as iridium, but is not as durable (i.e. will have a shorter change interval) and has much worse conductivity (if copper = 1, iridium = 3.5, and platinum = 10, lower is better).

I was watching horsepower tv and they put in a set of E3 spark plugs and they said they saw a small gain and they had better gas mileage. not sure about the price tag or how true it is but you might want to look into it if you do let us know how they look.
