KA24e-T spark plug question

[ftrs13]

Ive noticed that NGK 7s seem to be the standard, but I cant find them for the KAe. I was just wondering what the other KAet guys were using.

try http://www.ebay.com or some nice HKS Iridiumhttp://www.hksusa.com/products/?id=730

I've been using NGK BCPR7-11. I think if you go to Autozone or someplace like that you have to give them a car that the plug is made for otherwise they can't find it because they are just dumb. I might be wrong on this b/c my memory is pretty bad, but, I think that the 96 or 7 Saab 9000 turbo uses these plugs. I'm pretty sure that's how I got em' b4.

im running stock supra ngk plugs on my e seems to work fine they are one colder than stock for our cars

[ftrs13]

do you gap up the supra plugs ... I got a set of stockers, couldnt find the ngk, and they were gapped at .020, so I gapped them up to .030, and Im misfiring terribly in boost.

should I have just left them at stock gap, or just find the ngk and gap those up as well, or leave them alone at .020?

thanksSteve

if your miss firing at .030 its not the spark plugs fult, bad ignition wires or weak distributor might be a cuse

Why not? My friend's eclipse had severe misfiring @ 15PSI of boost over 4.5k rpm. We closed the gap on the plugs from .30 to .27 and voila... fixed.

But ftr... beware of that boost creep

yeah, Im watching for it, I realize that its a problem with the T3 internally gated, but I havent had any problems yet, Im going to redo the plugs tonight, and see where that gets me. I also have a new set of 7mm bosch plug wires, so Ill be doing that up tonight, and see where that gets me

your comparing apples to oranges, in a KAT a .030 gap is small enough so that misfire shouldn’t happen, but since its does the problem might lie somewhere else

Make sure that what happened to Structure does not happen to ya.

Checkered you are probably right, since stock is .44, right? Lowering the gap might hide spark issues elsewhere.

.044, I know some one with stock copper plugs at .044 running 9 psi without a problem.
