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.

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.
Hey guys I ******d up I gaped my plugs at .028 and I am running a 1993 stock 2jz-ge 5-speed . I now found out the gap should have been .044 I have to take the car into get smogged will this cause me not to pass 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
