Spark plugs for 3SGTE, which one is the best? Options

[Red123]

Hello guys.
What spark plugs should I use for 3sgte? Which one is the best?
Currently using NGK Iridium Spark Plug Grade 7, bought from fensport and I'm not very satisfied with them.

this is all been covered timdog your looping around in circles, yes Gen 2,3,4,5 use the same plugs.

copper is the most conductive but its also the softest and weakest they wont last long <---- Best spark, shortest life, available in all heat ranges, cheapest

iridium is supposedly the strongest, least conductive <---- good spark, ****good lifespan, available in all heat ranges, very expensive

platinum is the middle ground, and the one that comes factory <---- good spark, ****good lifespan, does NOT exist in heat range 7, very expensive


**** note: spark plugs are not magic, if your tune is out of whack, either too lean or too rich or too advanced or too retarded they will foul just like any other plug. if you have spark plug issues, this is a very expensive NON-FIX.


now has this made it bluntly obvious why people use BKR7E?

Stock motor, stock tune, stock power use stock plugs BKR6EP-8. saves you pulling off your intercooler

modified anything? go copper

making more power? go up a heat range
