gt4tosupra Posted June 28, 2014 Share Posted June 28, 2014 Would these plugs be ok in my tt 1jz Soarer std boost? I bought them for the v8, but then bought another set for some stupid reason, so these have done about 20 miles Heat range 20 is same as 6 in ngk terms.

Guest FullAttack Posted June 29, 2014 Share Posted June 29, 2014 6 should be ok.. Gap them to 0.55mm.. I generally use BKR7EIX on stock, and BKR8EIX when past 450hp. Link to comment Share on other sites More sharing options...
gt4tosupra Posted June 29, 2014 Author Share Posted June 29, 2014 Is that gap not a bit extreme, should it not be about 0.7. 0.8? Link to comment Share on other sites More sharing options...
Mk4Gaz Posted June 29, 2014 Share Posted June 29, 2014 Don't try to re gap iridium or platinum plugs, you'll likely ruin them. It's worth checking the gaps on copper plugs, but they're generally correct out of the box. Should be 0.9 mm from memory Link to comment Share on other sites More sharing options...
gt4tosupra Posted June 29, 2014 Author Share Posted June 29, 2014 If I don't touch em, these are 1.1 out the box, hence the 11 on end of the code. Says in this chart tho that their fine for a 2jzgte, so I'm reckoning should be fine for a 1jzgte? Link to comment Share on other sites More sharing options...
garethr Posted June 30, 2014 Share Posted June 30, 2014 The EPC lists PK20R8 for the Soarer TT and PK20TR11 for the VVTi. Link to comment Share on other sites More sharing options...
gt4tosupra Posted June 30, 2014 Author Share Posted June 30, 2014 Cheers. I'll sell these r11 then and get the r8 Link to comment Share on other sites More sharing options...
