ok this maybe a nob question but y does it matter if it has a projected ti. i mean what is the big risk of running it? Does it get to hot? do they burn off faster? what ? because i have heard of running the non projected tips but haven't really heard alot about them and are the br7ef's the plugs i should run because i just put a NX kit on my truck and im planing on spraying 250 to it
