It refers to the heat range of the spark plug. It has to do with how much
heat is retained in the plug. I think it's a function of how much ceramic is
in the plug. Generally you want to run a "cooler\lower heat range" plug with
nitrous and boost. Especially with iron heads since it retains more heat
than aluminum.

Can someone tell me what the following phrase means....'Running
plugs
one degree colder than stock....' What does it mean to run one
degree
colder. I didn't realize spark plugs were temperature
controlled?????
Oh, does anyone have success/failure stories about Taylor Vertex
wires???? I want the Magnecors, but, but.... Taylor has a nice Pro
wire set in Yellow.... I know, but I will ask any way. Are the
Magnecors worth the 90 bucks in the 8.5mm?????? If so would the 8mm
set
do a fine job as well???? I kinda want performance reliability and
engine dress up as well.... I kinda need yellow wires, but I
suppose
red will do....or even blue if I have too. Thanks.
