Would a cold plug like an ngk 3346 effect the idle and down low power of a motor and make it feel weak in lower rpms? My car feels lazy down low but pulls hard as hell in the higher rpm's. Im N/A for now an may be for a while. Should i put tr6 in to fix this? An is there any power loss between plugs? By the way the motor is an lq4, 243 heads, 64cc. With eps 226/230 cam on 114+4

Yeah mail order from frost, think a dyno tune would fix what im feeling?

You should be good with a stock heat range TR5, maybe a TR6 at most.
