spark plug and gap

[boost fiend]

ok, its time for me to change the plugs and wires. im thinking about going ngk for the plugs and another set of morosso(sp?) wires.

anyhow, i run about 13 psi only have a few diffrent mods. exaust, intake, yadda yadda.

so, i guess my question is, what is the stock plug gap and does anyone have a prefrence to plugs and gap? if ya need more info about the engine, ill sit it out.

NGK Copper

Stock gap run it and if it breaks down at high rpm/max boost close the gap down 5 thou and repeat.

thanks IJ!! now i just need the stock gap. sorry, looked and cant find it.

 

[Mr.PFloyd]

.8 mm as stated in the tsrm
0.031 in for them americans

 

[MassSupra89]

I run .029 and its smooth as butter, right around .030 should be good

 

[boost fiend]

thanks guys!!! real help!!! thats why sm rules all!!!

I run a 42 gap personally.

Haven't had a blow out yet.

The JZ's plug gap is .044. I would have thought the stock 7m gap was larger than .031.

yeah but id assume people run bigger anyway considerign saome peopel dont measure before thye drop it in :nono:

plug gap- the bigger you can run without spark blowout the better.

I pulled my old plugs out (the ones that were in it when I bought the car) because I was getting a pretty bad miss at full boost... and two of them were gapped to about .039, one was .035 and the other 3 were right around .030

Changed wires today...missing out at high boost...Time for new plugs.

Speaking of plugs, I need to find some flippin' deep welds......DEEEEEP welds.

:nono: I lost mine while in the transistion of moving.

FTW!

Gap mine at .28 and run Irridum plugs from NGK.

No spark blowout, or missing at high RPM and boost levels. (Up to about 25psi actually...)

Stock coils, and Moroso wires. (Have used NGK, Magnacore and stock, and the Moroso ones seem to be a great deal.)

 

[Boost Lee]

I'm gapped at .028.

 

[boost fiend]

ok, looks like gap is ok anywhere from .028 - .030
