NGK Hot Spark Plug
I read somewhere that theres an NGK Hot Spark Plug that Mazda used on the RX8 to minimize Hot starting issues...
So Are they still Laser Iridium Plugs like the stock ones that come with the RX8?
Any one tried them?

There is a stock "hotter" plug that Mazda used in colder climates to keep them from fouling as easy. I had them in my car years ago and didn't notice ANY difference
I run 10.5 or 11 heat range plugs at the track. they are " colder" plugs and they will foul if idled too long. They do lower the chance of detonation at higher cylinder pressures in extended WOT runs
