Are you sure you need a 2 step colder plug? What are the plug readings like? What damage, if any has been done to the plugs? If you have done plug readings, what method are you using? The most accurate method is the old British tuning method. That would be perform a full throttle run and without slowing down kill the ignition without locking the wheel of course. Safer of course is a dyno but the same technique applies. This will ensure the most accurate reading. Because the plug reading is not fowled by low speed cruising.

 

Greddy has 2 steps colder... http://www.i-m-racing.com/grrairloresp.html

 

the heat range of the plug is in the number, stock plugs are 5, one step colder , two steps colder 7....


just curious what you need two steps colder for, lots of high high hp cars on here running 1 step...
