I really dont recommend using the stock plugs for a sentra. They are heat range 5, thats two steps colder than stock SR plugs. If you are 10-12psi and in a 4th gear pull (engine under load for an extended period of time) you could quite possibly burn a hole through one of your exhaust valves, thats what happened to me from using those exact same autozone plugs. 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.
