Go to who ever sells NGK's and ask them for BCPR7ES-11, those work great. The 6's that xhdriver recommended would be the lowest i would go on heat range.

well Im at 7psi for now and holding (not doing anything else till I get my power FC power wise at least) and they were the exact same ones I pulled out of the car so I feel pretty safe with um for now atleast.
