i just bought 12 ngk bkr7e plugs from napa, i'm going to install them along with my turbo.

i was wondering if I need to gap them, and if i do, by how much?

 

yes sir! depends on how much boost and hp u making..and what type ignition system ur running

 

stock ignition, lookin for anywhere from 180- 200 whp on my stock d16

 

i gap all my plugs to .030 and have never had a problem. thats what i did on my stock 200WHP D16 as well.

 

anywhere from .028 to .030 should work

Perfect gap.

 

i read you can hit them off of a desk to gap them, how do you measure after?


also, does anyone know how big the gap is right out of the box

You heard you can do what??

Dont worry about how big the gap is out of the box...dont trust that. Just gap them anywhere from 0.28-0.30 and you will be good.

lmao now thats funny....

 

Did you purchase the BKR7E's or BKR7E-11? The "-11" are pre-gapped, but as someone stated, I would regap them all anyway.

Yes sir.

You never want to trust spark plugs that are "pre-gapped." It never hurts to just check.

 

gaps out of the box on those bk7's are like anywhere from .028 to .037. i've opened a million of these and i always end up re gapping them. never let someone else do your job for you. it's easy anyways.

 

theyre just the normal bkr7e's not 11's, i'll run down autozone tomorrow and buy a gapper, and see how that goes, if i have any trouble i'll ask

.025 - Advance auto zone or where ever, get a spark plug gaper (like $1) looks like a big silver dollar

I had mine before at .035 just fine when i put them in, then for some reason down the road it misfired like crazy under boost.

.025 is what my buddy said and he knows his **** (boosted gutted hatch running high 10's strickly track)

 

hmm, i'm sure you buddy knows his *****, but most ppl on here are saying .28-.30

i was gunna do .30 would .25 be better?

 

i always hit mine on a bench to gap them down..

 

i just did mines today i put them at 28

 

Ii would go with around .030. You really want it as big as you can before you start having misfire problems. I used to run around .032 with 350hp no problem.

 

I had mine gapped at 34 for a while... making 442, but just a street tune..

You are not going to misfire from a .025" gap. I've ran as close as a .018" before with no problems. Sometimes dizzy's arent tht great and the only way you can compensate is by closing the gap in the plug.

I said gap as big as you can w/o misfiring (from blowing the spark out). I wasn't saying you'll have misfiring problems from going to tight.

 

Ok... I misread what you said. But technically, you don't need it "as big as you can." Go smaller from the get-go and save yourself having to regap the plugs on the dyno.

 

.028, that's what i run
