alright i have an 05 gtp. its got 3" downpipe, power log, ported rear manifold, K&N FIPK intake, ceramic coated crossover pipe. i will next be getting a tune and an 180* t stat. what plugs should i run on this setup? i was looking at ngk but the safely modding your grand prix said not to unless you have a smaller pulley which i dont have yet. any advise?
 


no pulley drop? id just go back with copper autolite 606's or 605's after drop id go with autolite 104's if necessary.
 
ok i want to see what i can do with out the pulley for now. its my everyday driver and i dont need any problems.
 
Well, I’d say your choice should be at least partially based on KR. If KR is low now, stick with the stock heat range plugs (AL 606). If not try some 605s if your showing some KR.
 
im not sure what my KR is at right now. i have a friend tuning my car with an hp tuner he works for some performance shop out of chicago. i will probably drop a heat range when i drop to a 3.6 pulley
 


u should have slim to no KR with stock pulley and the intake and exhaust opened up with the mods u have.
