This is what I got. Don't try to gap them, the electrode will break off. Should be pregapped though.

don't gap them?:icon_conf
the gap on the ngks is usually too high for my liking out of the box. I bring it down to .28-.30. Never broke anything...
Always gap your plugs. If the electrode would break off during gapping, it sure won't last inside the engine:icon_conf

Thats probably because you guys are running the standard plugs like the 3330's or 6097's. Generally, you do not gap the plugs he linked to because of the brittle metals that they are made out of (Iridium and Platinum types)
On topic, I would just go with 6097's or the 3330's and keep up on your plug changes. They work fine and run about $2 each. Or you can get the stock plugs and pay $14 per plug. I believe that number is 3452 IIRC.

What are you talking about? You don't bend the center electrode, you bend the ground electrode. BTW, an iridium or platinum ground electrode is NOT entirely made out of precious metal, usually there is a small tab of iridium or platinium fused onto the end.
BKR6EIX, the one he linked has an iridium center electrode, and a regular steel GROUND ELECTRODE.
It EVEN SAYS on the NKG website:
I was just saying that it is very easy to break the electrode. If you have a steady hand the the right gapper, go for it. I'm just kinda careless sometimes. Sorry for the confusion.
Stupid question but if I buy the plugs recommeded on NGK's website, can I just plug them in?! I'm rather mechanically 'uninclined' and am just hoping this will help.
just get a spark plug coin from your local autostore. There's nothing to it.
I gap my NGK 6097s at .30
I gap my NGK 6097s at .30
with the ngk irridiums can i boost my 1j bcuz it runs hotter than the ngk 6097s? i've been told that they don't last long and boosting makes them detanate
u would always want to run colder if u plan on raising the boosts. Hot is not always better. I also heard that irridium sucks for 1jand2j but than again i could be wrong so someone correct me.
I took the Iridiums that i had for my 7M-GTE and put them in Since they were still brand new.
Mattjk Recommendeds Gapping at .28
I am not sure about the iridiums. Allot of people say they do not like them. I'll be updating my build thread once i have some experience with them in my engine.
I think stock you are supposed to use Platinum plugs like on the 7M-GTE
Just make sure you stay away from --->Bosch<--- Plugs
I believe the Stock 1J Plugs are the same as the MR2 and 2JZ plugs

Champion C63YC (#796) FTW.
Iridiums and long hard pulls don't like each other. I do believe that sub 500rwhp levels are fine for Iridiums, just get a step colder.
Copper displaces heat better. Sure, you have to change them out every other oil change, but they work the best IMO.

my buddy has iridiums in his bpu 1j.. and it was detonating with them.. I'm not sure on the heat range he used, but he switched to 3330s and it went away and hauls ass now..
