wow i need to wake up i am to out of touch , i did not know you had to change the plugs when doing your mods = 2 # 3# or 4# pulley /single stage chip,more air =improved stock box and trans shift mod?

 

who said you have to change the plugs with a #2 Now a 4, 5 or 6 pounder thats a different story

 

hey gator what about a 3#?

 

Haven't been paying that much attention myself, since I don't plan to install a pulley until I beef up the internals. What kind of plugs are you folks running with a 4# pulley? Will my NGK TR6s work, or do I need to change to the Densos? And how many miles are you guys getting out of the Densos?

 

btt

 

TR6's should be ok, but I would consider the denso's or the BR7's too. I ran my truck with a 4lb lower and 2lb upper with the Tr6's at a .035 gap. pulled them out to change to the br7's for nitrous and they looked good to me after a 500 miles or so.
