I have the Autolite copper 1 step colder. I set mine up at .043, I start spraying when I fill the bottle. First spray by the weekend.

 

I am using 0.036 with a 75 shot.

 

I would toss the autolite and get you some NGK Coppers. Then gap them between .034 and .036

 

They didn't have any NGK's when I went to get them the other night, I wil probably change them in a month or so.

 

i have NGK 1 step colder on my car. and i an planning to get NOS 50 shot dry kit soon. what is the recommended spark plug for my application?

also i never gapped my 1 step colder plugs when i got them. what is spec for the stock 1 step colder plugs?

 

what should i gap 1 step colder copper plugs to with y pipe, b pipe, cat, muffler, intake, UDP and a 50 or 60 shot of nitrous?

 

i have my NOS dry 55 shot gapped to .035

like plurco said gap to .034-.036 and make sure with all nitrous applications to use COPPER plugs.

ngk part # for years 95-2k1.... bkr6es-11 (one step colder, standard copper),,, bkr6e-11 (one step colder, V power tip)

 

I have intake, Y pipe, cat back exhuast...with a 75 shot...and im on stock plugs with stock gaps...

 

change ur plugs right away, stock platinums are no good for car when spraying..and off hand i think stock gap is some where like .044

 

what is the v power tip....and is it any better? so with a 50 or 60 shot and y pipe, b pipe, cat, muffler, udp, and intake, one step colder --copper plugs should be gapped to what?

 

85 shot

 

u know i couldnt really tell u which is better all it is the v power tip the tip is split down the middle forming a V i dunno how it helps or hurts.. we have to wait till someone who knows pops up (Jime). to gap them take a look at what everyone is posting and decide for urself where u want to gap

 

Im on stock plugs but there not platinum 's Im on stock NGK Copper plugs

 

oh ok.... stock plugs are usually platinums.... just moniter ur air/feul or egt and make sure ur not running to lean. and ull be fine

 

lol i wouldent know... ive been spraying for a couple mounths now with no guages

 

and no problems? as far as running lean?....if you don't have gauges, you could alternatively look at the plugs to tell if you are running lean....i believe if memory serves, the plugs should look kinda blueish if your running lean...

 

no clue never looked at the plugs.... i'll go pull one out now and take a look... and be back with a post

 

I dont know how long the link will be up but here ya go


Plug


Dosent look to bad...

 

link doesn't work

 

Oh well...they look good tho

 

Is there a reason why you should use copper plugs only when using nitrious? I have platinums now and they seem ok but if copper is better I'll use that.

 

This is from the NX Installation Instructions.

In stock engine applications and street usage the spark plugs should be at least 2 steps colder than stock. Do not use platinum tip, extended tip or any plug with multiple ground straps or split ground straps. When in doubt about heat range always go one step colder. A spark plug that is to “Hot” will cause detonation, burned plugs, poor performance, and engine damage. In competition
engines always use the coldest plug available.

 

Thanks! I'll go grab some coppers.

 

so what sort of NA power degredation should be expected with 1 step colder plugs gapped for spray over stock temp plugs with stock gap?

 

Depends on who you talk to and various other variables I guess.

Personally I don't see any degredation. I ran a 14.6 N/A with my auto with 2 steps colder, gapped at .035.

Others say they see a big degredation so best advice I can give is to try it at the track and compare.

 

I've heard that everyday driveability isn't grossly affected, most noticeable difference is poor gas mileage. Is this accurate?

 

Jime i bought those NGK's you use on your car and they were pregapped to .035 so i didnt have to change their gap. Maybe i wasnt doing it right, what do you say they come gapped with?
