All in all, what is the best plugs to use for a stock ecotec. I am going to install a 50 shot (that is what seems to be the safest on a stock engine). So I want to know what plugs are the best and where I can get them from. Any help would be appreciated.
some have used stock srt-4 copper plugs. you can get them at your local dodge stealership or parts store

depends on what stage plug you want to use, here are the two that I recommend from NGK...
One stage colder :
LTR6IX-11 stock no. 6509
Two stages colder :
LTR7IX-11 stock no. 6510
I think the one stage colder plugs should work out fine for your application, that's my opinion atleast.

my eco has been running great on a 75 shot with auto lite 103
i ran the 103's with no problem but id look into the champion plugs because they are the right length
