Stock for a GT4 is NGK BKR6EP-8, It's a long life platinum plug with a 0.8mm gap and heat range 6.
An upgrade into the next step colder heat range would be the BKR7EIX which has a 0.8mm gap and a heat range of 7. From NGK QUOTE A rule of thumb is, one heat range colder per modification or one heat range colder for every 75–100hp you increase. So if you're taking your car up to 300+WHP, It might be a good idea to get the BKR7EIX, This is what I'm going to be doing. EIX is the Iridium IX series. They don't make a laser platinum in the 7 heat range for our engines -------------------- Mike W
