NGK BUR7EQ, BUR9EQ, R6725105, R6725110, R6725115 -- those are the plugs FC guys need to run. FD guys can use the B10EGV's that are using the PowerFC but that is a pretty cold plug for the street. The issue of having a resistor-type plug for use with the Haltech and Microtech setups is critical from what I understand as there's a potential for a noise problem interfering with the trigger. This is for street cars.
For anything over stock boost/stock power levels, absolutely do NOT use BUR7EQ's in the leadings. Swap them out for 9's.
Road-race guys who are seeing lots of load for 20+min at a time need a substantially colder plug; atleast 11's all around.
The issue isn't horsepower per se as that's a fallacious way to rate the use of plugs but rather is an issue of load and more-so chamber temperatures. Try those same warmer plugs on a road-race course and you'll see them be much more prone to turn into glow-plugs. Those that use AI with alcohol/water can get away with using a hotter plug as the chamber temperatures are (usually) much lower compared to gasoline-use only.
Get a stout enough ignition system and you can use colder plugs that won't foul. Bang, bang!
Spark-induced misfire due to a glowing spark plug is brutal and can be fatal to a rotary. I've seen it three times.
