i need a quick answer:
my buddy needs to get colder plugs for his ranger so he can get rid of spark knock. how do you tell if one plug burns colder than another. i don't know shit about spark plug numbers and all that.

what is the easiest way to tell the kragen moron which plug you need, because i know those guys only read from a book and think thats the only part that will work.

also, if there is carbon buildup on the plug it will be a grayish white ashy knd of color right? the chiltons i have isn't in color so it doesn't help much.
