When ya'll say one step colder spark plugs? I am confused... someone help me here.

 

spark plugs have heat ranges. the difference is in the electrode and porcelen. a hot plug will retain more heat than a cold plug. a hotter plug is better for emmissions and n/a motors. when you start modding a supercharged motor you want to go with a colder plug to reduce detonation.

 

can i use colder plugs stock?

 

no reason on a stock car

 

at what point does it become beneficial however?

 

dropping pulley size....it helps reduce KR (knock retard) which kills performance by retarding the timing to save the motor

 

lol when you don't have said pulley

 

danm i went up 70+hp over stock and im still on stock plugs,lol...i think its time to buy new one's

 

then how about 2 steps colder? other that KR is there anthing else to gain? hp, gas milage ext...

 

I'd agree

 

not really. you'll foul the plugs quicker lol

 

what plugs do you guys have?

 

Ngk Bkr7e

 

stock and if I do end up needing them I'm sticking with Delcos (of a different number)...period

Delco/OEM ignition seems to work the best no matter what power your car puts out

 

What colder plugs are you guys running? What should I run? Mods in VBGarage...

 

i ran brk8eix, its 2 steps colder, and iridium.

they are like 10$ a piece but very nice, i also gapped them at .32 and it ran very smooth, also picked up some gas mileage!

 

^ I'd switch to copper

Iridium stores more heat. Copper dissipates heat faster.

 

anyone have the link to the zex plugs..i want to get those,but i cant seem to find it on there site..i find there plugs,but do they fit the balt,i dont knw

 

ngk doesnt make a 2 step colder copper plug that i could find.
