So I've done some research, seen alot of banter and not much fact on why you should or should not use Iridiums in a DSM.

The facts I know, Iridiums take less voltage to spark than an copper plug, all other elements equal. Iridiums are also 4x more expensive.

I would think in situations where misfiring becomes an issue, Iridium's might extend the conditions the factory coils would work in.

What I don't know is any side effects in a DSM to using them, other than cost. I am not expecting them to be some 100k mile plug in there. Just don't want misfire issues.
