Yeah, have had no problems related to the plugs. I had an incident this weekend that I think is alternator / voltage regulator related (more as I get more details about what went wrong) but plugs have been find.

Thanks Dave... Cmon F.I. guys... what plugs are you running. Denso, NGK, Stock??? It's my understanding that you should be running a colder plug with F.I setups... I'm curious what everyone is running with their setup.

I thought I had read a few threads where people switched from the OEM plugs and encountered problems. Just becuase the Supra guys are doing it doesnt neccessarily mean we can, remember we have those tempermental computers and such to deal with.

Guys, I'm really confused on this.. Some of the major tuners like SRT, Turbo East, Power House Racing all supply a 1 step colder plug with their kits. Is it because the kit is for the 2jz motor and it needs a colder plug? After doing a search on many forums, it seems like the NGK 3330 is a very popular spark plug for boosted GS/IS vehicles... Your thoughts? Maybe the GS400 has such a solid built motor that it can handle the extra heat from going F.I. thus can use the stock spark plug with no problems
