Double platinum is what comes with the VQ from the factory. We like using the iridiums because they last longer, have a more consistent spark, and are also cheaper. But it all comes down to personal preference which is why we offer the different choices.

plug temp has nothing to do with outside temp, as we state in the first post they are for forced induction vehicles, unless you are running a custom tune, then it is upon the tuner to recommend the proper set of plugs for your vehicle.

For the VQ there are some things in the way, would not recommend for everyone. But you if you can do basic bolt ons should be fairly easy, there is a DIY on my350z as well to install them.
