is a colder plug better?1wykdmk8 said:Call Max (1-800-866-1520 x 236)and get the stock lightning plugs. I have them, and run them exclusively. They are a 2 step colder plug.
driller said:A colder plug is more resistant to detonation. Hence, timing came be advanced further for more power without ping.
The downside is that too cold a plug will foul easily depending upon driving style, mileage, etc...
I have not seen any benefits in my experience from rare metal plug construction besides longevity, but I have not tried Iridiumn and I would hesitate to call them garbage.
Back before I knew better, I ran Bosch platinums. Upon my last plug change, I went from Autolite 764 to Motorcraft AWSF-22C(copper - one step colder). My next plug change will be AWSF-12C(copper - two steps colder).

what do you gain from it? sorry i always thought it was a ping detonation thing i never knew you could get performance from it.
