i got speed in cool.weather

90F+ hot?
That is the morning LOW temp here in Phoenix this time of year, 91F the last few mornings, and it just goes up to triple digits all day from there.
I think however it's the humidity in the air that makes the difference in you incoming air.
It's denser and the water content in it can't help.

All I run here in the dry heat are Iridium plugs.
NGK 5944 (BPR7HIX) for 2-stroke.
NGK 7544 (CR7HIX) for 4-stroke.
If a build has a problem, the plug is the last place I have to look.
Okay great, however do you know of a good iridium plugs for humid hot weather? Without having to rejet and all that other stuff.

Monsoon arrives tomorrow, that plug has always worked for me and I have never had to re-jet to compensate.
