part # for JDM st205 spark plugs, spark plug part # please Options

[injection]

Hey guys, cant find spark plug reference # for JDM st205 engine, even in our st205 part reference section, it has the part # for ignition leads, and alot more items, but not plugs, at least from what I can see,
does anyone have that #, would really help me out if you could post it. If I had the #, Im sure my local parts dealer could take that, and go one step further and order the #7 heat rateing, either NGK V-Power, or Bocsh platinum +4, these plugs both have the same thing in common......Big Spark,

Thanx you guys, Rav, Iridium
Smaay, IK24 it is.......
Def. going with the Ik24, I think you can vouch Smaay, regarding my other post about high boost....as well I have popping out my exhaust around 5500rpms, am running NGK V-Power right now, with about 6000kms on them total......People say spark plugs tell a story about your engine, I pulled one out, and its black ( sutie ) around the bottom ring, and very white up top, I def. have a hot burn! and believe I am leaning out.......hence why I am trying to lower my boost, but this should help, to run a much colder plug, and Iridiums at that.

Will try this # for the plugs at my local parts dealer....
