Hey whats up everyone so ive tried searching and looking through post i couldnt find the exact answers im looking for about what i should be running....

Some basic info about my setup is ZPI stage 1, 550cc Injectors looking to tune to around 300whp go a full megan back exhaust beside the 3'' dp the kit came with, agency power pulley, 38mm WG open dump, HKS SSQv, yada yada yada

I just ordered some NGK step colder plugs that come pre-gapped to .44 i know your not suppose to gap iradium plugs but ive seen post people gapping them smaller

What should i gap my plugs to before my tune? Should i leave them at .44 or go to a tighter gap?

SVicksTC

Right now im running the stock plugs, but as much as i drive the car being away at school its fine until the tune

I'm using 1step colder NGK iridiums and I'm at 275whp. You'll be fine - gap them to .32, just take care while doing it.

Alright thanks for the info...how easily do these tips break?

I guess ill just be mad careful

B_Real45

Not sure as I've never broken one

But just a few light taps on the tip should bring it down.. use a gapper to double check the gap.

yeah reducing the gap should be easier, increasing gap is a lil tricky i broke 3 so far and was being very careful at all times

I have NKG Iridium 2 Step colder @ .044, what do you guys suggest gaping those at?

prolly .035 or a little less

btw i thought the ngk bkr8eix came preset to .035......I could be wrong

all4degame

i thought they were .044, I bought them from Dezod a few weeks back. BKR8EIX Stock 2668

B_Real45

If they had a -11 at the end of the p/n, then it's pregapped to .044"

I have mine at .032"

all4degame

Mine does not have the -11 on it. Paul can you chime in and clarify?

dezod doesnt sell the (atleast on there site) bkr8eix-11 (not sure if they even make them)

so yours should be pre-gapped to .035..........either way your ok mang

all4degame

If they are at .035, i'm gonna leave them at that and see if I have any problems, if I do i'll make the gap smaller

i didnt gap mine, i got the same as you and there doin pretty good.......i havnt noticed any promblems with em......if it isnt broke then dont fix it.......lol

purplenitroustc

between 28-31 thousandths for colder plugs.. easier to fire at a smaller gap

SVicksTC

I ordered NGK bkr8eix-11 they are 1 step colder and pre-gapped to ,44 im going to take b's advice and gap them to around .32 I guess i should order a couple extra before i attempt to put these in before the tune in case i break one

crush02342002

if you got one step colder then you got bkr7eix-11(bkr8eix is the two step colder plugs)

not trying to bust ya *****
