The car comes with NGK platiniums, I have Denso Iridiums. Can't tell no difference. I do know the Iridium will last longer though. Yes you can use copper, but why?

NGK Coppers if you don't like wasting money. No performance difference, and cost about 1/6th as much. They are like $1.59 at any auto parts store. BKR5E-11. In my opinion anyone buying anything but these is simply wasting their money.
if u wait 30k to replace spark plugs, NGK coppers protects you from economic phenomenoms 
like gas price

The truly obsolete plug type is platinum. The only reason platinum plugs exist is that it wasn't until a few years ago that better metals could be used cheaply. Iridium is harder, conducts electricity and heat better, and has a much higher melting point -- which means longer life and a better spark with a finer electrode tip, which reduces strain on the electrical system. Now that iridium plugs are available, there's no reason to use platinum.

It takes approximately 10 minutes to change all 6 plugs though... it's not as if it's a difficult procedure. I see what you're saying though, especially for the mechanically challenged.

Personally I just can't justify spending $60 on spark plugs when I can spend $10, even if I have to do it twice or three times as often. They are so easy to change, and checking them is also a good way of monitoring how well your car is running too.

NGK coppers for all the reasons listed before, and Nealoc is very right with this assertion, you get a look at how each cylinder has been running more often.
Not only that, name me a metal that is more conductive then copper. Iridium? Nope.. Platinum? Nope..

I have my original NGK platinums in and at 63K, mostly highway miles, and 11.5 years later my engine is running as well as it ever has, and my fuel economy is better than 95% of the 4th Gen members.
I'll stick with the platinums!
