The ones that are not so cold that they foul quickly but not so hot they wear prematurely

I think most top dawgs are using these- NGK R6725-11.5. Get ready to spend some cash though at 40 bucks a piece.

I'm running NGK B11EGV plugs in my car. They work great for my 21 psi, 1/2 bridge, on pump+meth, but i have no idea if they would work well for you. One plus is that they are dirt cheap, like $4.xx a plug, so you can just give them a shot and find out.

I was just looking through the NGK catalog this past weekend and the only plug they offer that is carried by sparkplugs.com that is available in a 10+ heat range and the proper reach (.846", same as stock) is the R6725-xxx. NGK also lists an R7420xxx which appears to be an Iridium version of the R6725xxx but sparkplugs.com does not have a listing or price for it.

The EGV and EIX which I have used with good results have a .750" reach. Meaning the flash point is moved back about .010". Does that matter? Don't know but at very high boost one would think it might help to have the flash point closer to the chamber. Also, the EGV and EIX plugs are non-resistor and that could play havoc with electronics.

NGK R7420 a.k.a Trust/Greddy RE9/10/11. These appear to be a new and slightly improved version of the R6725. Typically $25-30USD on the internet.

rockauto carries a NGK BR10eg (resistor) stock # 3830. same size as the ###EGV

been working for me?? I heard, add a deg or two of timing since the plug is shorter then stock.
