bosch PLATINUM+4 part # 4431
or
bosch PLATINUM IR FUSION part # 4516
or
Pulstar Plugs (heared they miss fire for about a month or so)
or something else

I was looking at this site.

Comes stock with NGK Plats. I'm running NGK Iridiums. Denso is another great choice, albeit fractionally more expensive. I wouldn't get Bosch.

I use NGK copper. My tuner hates NGK Iridiums because two have come apart on motors he has had to rebuild. (he did not build the motor the first time, the plugs came apart in the stock block)
