I have 1 step colder plugs now but someone suggested 2 steps colder. Im looking to get my car ready for tuning. Anyone know which plugs I should go with I have:
12 psi pulley setup procharger
high flow fuel pump
rc440 injectors
oem intake, oem Maf
large aluminum radiator
Gonna add the Emanage Ultimate then tune


Thanks!!

 

1 step colder will do the job well..

 

ngk right... I think I have a set I wonder if I should buy new ones, They flooded out once on me....

 

buy a new set just to be sure.. NGK irridium 1 step colder..

 

i agree one step colder should be fine....u shouldnt have any spark blow-out

 

Thanks guys Ill grab a new set of 1step plugs
