Hey guys i have a 92 Sc300 with a 1JZ all i have is a fmic and intake on the car but have the boost at 14psi on stock turbos......does it really matter right now what NGK plugs i run? do they have to be the iridiums or can they be the V or G power ones?and what should my gap be since the boost is turned up?

Thanks so much guys!!!

Gap should be .26-.28 and you should use NGK 6097's I think, I'll check to be sure.

The 6097's were replaced by NGK 4644. Same exact plug just different number.

You are correct.

Do not buy plugs with platinum because platinum gets too hot.

I've used several. These work great. Gap to .28 for your 1J Turbo Setup.
Makes a huge diffrence in smoothness and idles better than all other plugs
I have used and i've gone through several types. Get them on Ebay.

I say ebay because none of the 4 parts stores in my area carry them.

You can get the 4644 (old #6097) from any parts store. They are less than $2 each.

Just posting to verify the many others: 4644 gapped to 0.028 inches (not 0.28 haha). That's what I'm running and it's fine. I wouldn't recommend platinums because they foul easier and they cost a butt load.

get ngk bkr7e's had those previously or ngk BCPR6EGP which is what im running now
just gap them to .026(thats what mine felt right at, just start at .028 and work your way down) and i taped up my coils and wow... idles perfect and doesnt break up in the higher rpm anymore

ive heard this from multiple people as well
colder heat range plugs for turbo motors help keep it from pre-igniting
and finding appropriate gap of the plug your using can eliminate misfire and car breaking up
that's what Ive gathered from trying different plugs
just my $0.02
