NGK non resistor type spark plugs

so ngk's heat range from 2 being the hottest plug they make and 10 being the coldest plug they make. the hottest i can get for my da is a 4 which is actually the second hottest seeing that they skiped 3 for some reason. only problem is that its a non restistor type plug. other than radio interference (not a big deal because my stereo sucks anyways) are there any other issues i have to worry about?

Yes, the interference that gets in the radio will also get to the engine management system. If running a stock ecu with any Hondata system you will quickly find out how bad it is!
