BKR5EIX-11 Iridium IX Spark Plug
I have searched but everyone is using slightly different heat range etc.
But is this the correct model for NA 2JZ-GE?
What is the gap supposed to be on the -11, will it come with correct gap for my car .. I would double check tho

yes a heat range of 5 is the stock heat range for a non turbo 2jzge.
1.1 means it comes gapped at 1.1mm or .043 in which is the stock gap.
so a bkr5e -11 is a stock copper plug, and a bkr5eix -11 is a stock Iridium plug (the one everyone should use).
a stock 2jzgte uses a bkr6eix -11, however at higher boost levels most to a bkr7eix (or bkr8eix for even higher boost) and gap them down to .032 or lower. IF you get the version without the -11, they will already be gapped at .032. If you get the one with the -11 it will be gapped at .043 which is too much for bpu gte or apu na-t.
on a stock sc300, I would drop in some bkr5eix -11 and enjoy them for 60-100k miles, which is nice because its a pain to take the stock intake off. Platinums last this long but the spark energy is not as good as the Iridium, and tend to foul out faster.

I went to NGK.com and put in my car(93 SC300)
It lists BKR6EIX or BKR6EP.
But on this site it lists heat range 5 for the 2JZ engine in general

5 is a hotter plug is there any issues

I just went to NGK.com and tried it with 1992 and 1994 and 1995 and they all come up as a 5 range.
1993 is the only one coming up as a 6 and that is most likely an error.
you will not have any issues with the 5 because 5 is the stock heat range for a sc300 using NGK plugs.

yeah its not that bad but still a hassle if you are stock the coolant lines aren't fun to deal with.
If you are turbo like me you can't just slide the throttle body off the studs because it hits the turbo housing, so you have to slide back the throttle body as much as you can and undo the 2 studs with some pressure pliers, and once you get those out you can remove the throttle body.
