spark plug gapping for NGK iridium plug

i'm about to install a set of these suckers into my 2.5L millenia. Does anyone know if i have to use a gapping tool to gap the plugs to a certain measure before installing them? In my other car(maxima), i installed bosch platinum4 plugs, and they were "pre-gapped" in-box...not so sure about these NGK iridiums though. in any case, do anyone also know if the iridium plugs perform well in the millenia 2.5L engine? thanks in advance to your reply

I just got some spark plugs from Autozone..
I don't think they were the right ones (copper plus, lol),
so I didn't have them installed yet.

But the gap on the box that they wrote was .044

Are the NGK iridium what is suggested for the 2.5L engine ?

thx, hope this helps.

thanks for your reply jens_millenia.
I figured out already that the plugs come pre-gapped in-box. I still havent installed them yet due to lack of long extension for a torque wrench set to reach the plugs in the engine. k, hope you get yours done soon too. lates
