wow from what i learned at the tuning seminar by ben strader yes you can actually get a too cold plug what happens is that it does burn correctly on the electrode strap. what you want is actually a colored rainbow color, on the strap too cold or too hot and too much retard and too much ignition advance will cause that rainbow color to move up and down.

I'm using Apexi racing plugs #8...they are actually better than the NGK's I had. Unfortunately they cost $12 EACH

Re: Can you get too cold of a spark plug? (MiraiZ)
heres my suggestions.. buy regular plugs for the street use and another set of sparkplugs for the track.. i suggest iridium for the track.. and 1 step colder for the street.. i mean the iridium plugs should last for a long time since its gonna be used only so often just down the track and back...after that just swap it out.. doest take long anyways just keep a wratchet and extention and socket for the plugs and your all set...

i'm still running stock plugs/heat range. don't seem to have any probs at 8psi running 1/3 degree of retard per pound of boost. does this sound right?

BTW which is colder BKR7E (shorter/recessed insulator) or 7FR5J-11 (longer/extended insulator)

Re: (Turbo E)
On my 99 Civic Si, the BKR7E copper plugs were 1 step colder than stock. But I'm using some BKR7EIX-11's Iridiums which are 2 steps colder, which is way too expensive, and an overkill, so I'll be going to BKR7E.
Besides, I'm only pushing 5psi.

Not to say they aren't good, but I'd wager they are made by NGK/Denso. I don't think there is any way that Apexi manufactures plugs.

Re: (Snafu-Si)
FWIW the BKR7E and BKR7EIX-11 are the same heat range. The "7" indicates the heat range. Higher is colder. The "-11" signifies the pulg gap (-11 = 0.044" gap).

you're probably right...they look suspiciously like NGK...I guess its just the lower heat range that makes my car run smoother...
