Strange idle problem with GTM SC Stage 1

I dont think your understanding what I said earlier. Not trying to be a *** when I said that, just want you to have all the knowledge so please understand that. There is no one step colder plugs for our car. The stock plugs in your car are the same ones the GTR use. The heat range on the stock plugs is heat range 8. There is no colder plug then that on the market currently. Just don't want you to go buy heat range 8 plugs thinking your getting colder ones when in fact your putting the same ones in your car that you have currently and end up wasting money. Like I said earlier your spark plugs are not the problem. Like Jordo said you would have a CEL if it was.

Frank just to clarify couple things Here

The GTR spark plugs are not the same as the 370Z plugs, also HkS does offer one step or two step colder spark plugs.

Hmm weird. considering the fact on HKS website they show the heat range 8 plugs having the same exact part number as the one for the GTR. Also when I went to the dealership I was thinking of getting the GTR plugs, thinking they would be a little cooler and after pulling up the info he said they were already the same exact heat range already the two plugs and using the referance chart it would be equal to a heat range of 8. I just checked NGK website and they are also showing the same part number on the application chart with the OE sign.
Hmm guess I am wrong, just weird there is someone else on here who said he got the same exact information.
