gapping copper NGK's
 

for those of you who went back with copper NGK's what did u set the gap to, i looked in the manual and it didnt say and specifications for the platinum ones

same spec as the plats, .039-.044".

they are pre-gapped per stock

SO what? How do you know the gap didn't change during shipping? Like I said many times before, anyone who doesn't check the gap on the plugs before he installs them is a DAMN MORON.

i'm just saying they are pregapped. didnt say anything about not checking it. geez what crawled up your butt.

Why did you say if it's not what he asked?

just trying to provide some information to a fellow orger. information is good, free information is better.

why the hell would you got with a ****ty copper plug when OEM is 2 prong plaitnum??

Shows how much you know, coppers are not only a fraction of the price they function just the same. The only difference is platinums last 60K vs Coppers 30K... When your paying $12 for coppers and $60+ for platinums its pretty easy to figure out those numbers.

And by the way copper is the second best conductor of electricity... second only to silver

OEM is 1 "prong" for platnium you probably talking about Botch +2 they have 2 "prongs" but only one is used to take away the heat.

and also. platniums are just regular coppers just platnuim coated for extra strength

:sprint: forgot to mention that, the platinum just lets them last longer... which in my opinion its not worth it.

i kinda like platnums :-)

Can you feel any differences between copper and platinums? How well does copper hold up to heat? Also does anyone apply anti-sieze to the threads of the plugs on installation?

If my car recomends NGK PLATS Then that's what I'm going to use unless otherwise. Mods I mean :grinno:

Check this site for more info Copper vs Platinum
I'm using copper after my first plug change with no problems...I believe the plugs came pre-gapped at 0.035. Platinums are recommended since they last twice as long but if you do the math, you can change copper plugs 5 times before reaching the cost of platinums.

If they are pregapped to .035" then I suggest you re-gap them as that is out of spec for the max.

:) funny. DAVE Sz is always helpful in getting people to find information on their own, pointing out a stupid question answered in stickies, having people sympathize for the original poster and answering the question at hand, ****ing the original poster off. He's a douche at times, but he gets the job done I think. He'll probably answer to my thread and ****t on me for all I know.

Where's your thread?

my NGK coppers came gapped at about .044 each; a little less on a few of them.. so I gapped them all the same.

I also wholly agree, I've read some articles about copper vs. plat plugs. furthermore, talk to anyone with a lot of experience with nissan engines and they will tell you ngk coppers are what to use unless you want to spring for plats which perform the same/worse due to worse conductivity of electricity

Haynes suggests 0.043 for the platinums but they have nothing about copper. If you have some better info on the copper plugs let me know so I can decide if to re-gap the plugs.

Haynes is wrong then, .039-.044 are the accepted tolerances, copper or plats.

How is haynes wrong when they are within the specs you say. .043 is between .039-.044. Just because they don't give a range, does not make them wrong.

If they're not 100% correct then they are wrong.

man i hope you never have kids... lol :grinno:

so NGK is the best choice for spark plugs?

the rule is that you can achive the most power by gapping the spark plug to be big without the spark blowing out.

Just a little extra information. If the NGK spark plug product number ends in -11, such as BKR7E-11, then they are pregapped to 1.1 mm, which equates to about .043". (That may be where Haynes gets their gap number.) If there is no -11, such as BKR7E, then they are gapped to ~.036". Don't know what tolerance they use when gapping.

DAVE Sz has been added to my list of forum idiots so I'll know not to waste keystrokes on his posts.:rotz:

Forum idiot, ha. Give me a breake.

By now I would hope that many know that the 11 at end means the plugs are pre-gapped. The thing is that during shipping the gap might have shifted a bit and just to be on the safe side everyone should always check the gap before they install the plugs.

um, that link says the following

Platinum should be gapped at 0.039in to 0.044in and Copper at 0.031in and 0.035in.

Hmm, obviously we have differing information here. Can I get a final verdict here?

Is it.... .039" - .044"

http://www.ngksparkplugs.com/apps/ca...uv/results.asp I don't know if the chart is suggesting .044 or they come gapped to that. But all are the same. They do make'em so I'll trust they know what they're talking about.

i have my coppers gapped at .044 and it's been fine for what it's worth.

I set mine right at .041-.042. That way they are right in the middle of the allowed tolerances. Also if the gapping tool is off by some I still know it's within spec. If I set it at .044 or .039 the plugs may be out of spec and I wouldn't even know it. ??? seems to think that if the engine doesn't blow up it's fine. Checking the plugs every few thousand miles is a good way of preventing a bad thing from happening. This way you know if you're running lean or rich.
