its already established that straight copper plugs are what our engines like best, but they dont last long. so the iridium is supposed to find a "middle" and still get most of the advantages of copper yet more longetivity.
someone correct me if im wrong.

and also, what is a good gap to run these on? and anyone know the torque rating for the plugs?
10-16-2008
Get copper plugs. Get 605's. Run a gap of 45. Just tighten the plugs down. If you would actually torqu the plugs you would probably need a torque wrench that has inch pounds instead of FT. pounds.

You wan't the hottest spark you can get without causing any KR.
10-17-2008
ok, how long will these last for approximately? so i know when i need to change them
10-17-2008
Change them out at about every 8000 miles.

.045 gap? I thought .055 was the recommended.
10-17-2008
I've never ran a .55 gap...not even now. To be honest i'm not sure what is oem specs but i don't belive it is .55. I could be wrong though... One time I was....just once though....lol

i plan on going down to a 3.4" or 3.5" pulley after a couple more mods... should i still go for the 605's or the 104's?
10-17-2008
wELL IF YOUR NOT GOING TO GO TO A 3.4 OR 3.5 WITHIN 8000 MILES THEN JUST GO WITH THE 605'S TILL THEN. But yeah once drop to oneof those thats the plug you'll need.
10-17-2008
yea... i plan on going down to a 3.4 hopefully within 8000 miles... all i really need is the powerlog, the 180 tstat n the plugs n i think i should be good enought for at least the 3.5", maybe even the 3.4 then im gonna scan her up

OEM is .060 I believe. 0.55 would be half an inch.Originally Posted by TDCRacing

10-27-2008

10-27-2008
