i dunno if this has been covered or not, i need to get my car tested for emmisions today and figured i shud probably do it in some new spark plugs. ive heard of people running bur9eq's on all four after intake mods. i have a drop in filter. would runnign the higher temp plugs help me pass emmisions? or gain any power? i have a TII

 

help? I suppose they might, but you're thinknig of maybe a .0001% increase in "help".

IMO its a good alternative if the shop is out of bur7eqs

BTW, its been covered MANY times, search.

 

there lower temp plugs so they will if anything help you fail emmisions. Power, probably not,.. but they will help reduce the chance of detonation. And they will make your plugs last a bit longer.
