CAMARO6 - View Single Post - Spark Plugs For Procharger in Cold Climate

I just placed an order for the P1X Procharger, with Stage II intercooler, for my '16 SS. I started reading through the installation instructions and noticed that they recommend using an NGK 6510 spark plug (which are a heat range 7, and 2 steps colder, from what I can tell) gapped at 0.35". This has me a little concerned, because I currently have a nitrious system installed (I'll be removing it when I install the Procharger), so I've been running NGK 6509's (heat range 6, 1 step colder) and I have a fairly significant problem with misfiring (yes, I do get a code), and the car bucking, when it's cold outside (anything less than about 50 F). I live in central Illinois, so it does get cold here, and while I rarely drive the car in the winter, and never if there is snow and ice on the ground, the late fall and early spring mornings are still relatively cold.

I've read through all the posts I can find on this forum, regarding plugs with the Procharger, and while I've seen several people mention a rough idle during a cold start, they also all seemed to mention that it went away rather quickly. In my case, with the 6509's, it could take 5-10 minutes, of warming up the car and/or driving around town, for the car to warm up enough for the misfire to go away, and I would expect this to be worse with 6510's.

So, are there any recommendations on what I should use (6509 or 6510)? If I continue to use the 6509's with the Procharger, am I going to continue to have the same misfire issue, or will the supercharger help eliminate that?

Also, this year, I switched back to factory plugs when it started getting cold outside. so since I've yanked on the wires a handful of times now, and will need to do it again when I put in the supercharger, I'm considering replacing the wires while I'm at. Any suggestions for what wires I should use?
