3800 Spark Plugs Question

[MIKES3]

My buddy just purchased an 01 GTP. Were getting the party started and he asked me what spark plugs he should put in. I am not sure because I went straight to Autolite 104s. He is bone stock at this point in time, but I am wondering if it would be ok to slap 104s in because he will be getting Air Intake, pulley and exhaust and what not in shortly. Will it effect anything.

What stock plug should I go with if I cant go colder?

I run 104s and I only have a catback, 3.4 pulley, and an open cone.....and my car runs great. I would tell him to wait until he has at least the smaller pulley before running the 104s though.

i agree with SYP .. run the 605's then move on to 104's when you do your mods
those rear plugs are a b***h to do
