I read in safely modding you gtp you should put colder plugs in but does it give you any hp gain and also i heard that you should use stock wires since they have a low fail rate.

What do colder spark plugs do? Headers add more flow and protect agianst KR so what do cold pluggies do?What does what do?
Colder plugs have less porcelain (the white part) than hotter plugs. The more porcelain the more a plug retains heat, in high HP cars where there is more heat it creates a hot spot in the cylinder which can lead to detonation. A hotter plug has a better lifespan, but obviously you want a colder plug that would retain less heat and NOT create that hotspot.
Gapping doesn't really have anything to do with the heat of a plug, but obviously a tighter gap under boost would lower the chance of spark blow out. It's different on every car though, for example, mine would blow the spark out at .030, but is fine at .028.
