A lot use the 3910x but it’s a pretty cold plug. We use the -7 and -8 NGK plugs in our clone and clone cousins...
 
Thanks Oval...I hate to sound stupid, but, does that plug have a specific number that i can look up.. -7 and -8 doesnt tell me a whole lot. probably should have posted in beginners forum, cuz thats what i am...

Yes... just be careful of your heat range NGK goes opposite. The low number is the hottest the higher the number goes the cooler your heat range gets
