GE/GTE spark plugs.. whats the difference??

[mike86supra]

hey guys i have the GE spark plugs in my GTE engine and i'm wondering if there is any difference in its firing, today i'm diagnosing my car for spark and fuel, car doesn't start just cranks

Heat level. I believe GE are level 5 and GTE are level 6.

im pretty sure i bought gte plugs and the part number also goes for ge its denso iridium #IQ16 5301

You just always want to go with a step colder for better boost

oh ok so everything should be fine, i'm trying to diagnose a no spark problem and just wanted to check with that first, thanks

Yes, just heat range. N/A are Denso 16/NGK 5, Turbo are Denso 20/NGK 6.
