Hey guys! I am going to a 3.5mps today, and was wondering, should I go one or two heat ranges colder on my plugs? Is there a part number for the autolite 104s or is 104 the number i need to ask for? Thanks guys!

i'd go 2 heat ranges colder if you have a tuned pcm...if not jus go one

use 104s. the part number is 104s. ask for autolite 104s. dont tell them what car its for because theyll try and tell you youre wrong.

Put the pulley on, scan for KR and then drop to 104's if you have KR.
You want the hottest plug you can run without knocking.

On a 98 with the mods you have you'll be fine with a 3.5. If you do get any knock you should be able to tune it out without going with drastically colder plugs just yet.
