I have the BKR5EIX iridum plugs right now. Getting some work done and would like 1 or 2 step colder plugs. If i can get iridium plugs i would like to have them. Would BKR6EIX be one step colder and BKR7EIX be two steps colder. If not ill just go with coppers since i already know what the step colders are. Thanks for anyhelp. If this isnt the right section just move it i just put it here b/c im FI and usually colder plugs are used in FI car.

You are better off going with copper plugs.... much better for boost.

6's would be 1 step colder.

I dunno I am still using 1 step colder. I used 2 step colder before and didnt notice any difference.

i was just thinking the iridiums because thats what i have now and maxmods.dynos or something like that said the iridiums were better for FI and nitrous cars.

Iridiums will work just find as will coppers. If you are making tons and tons of power then iridiums might work better, but pretty much any supercharged max has no reason to use anything other than coppers in my opinion. Coppers are like $1.50 as opposed to $8 or whatever for iridiums.

if you have 200+ hp over stock then you might want to go with 2 step colder plugs.
