After quite a bit of reading, I decided that the Denso Iridium plugs look like the best. I liked them better than the NGK Iridium plugs because the Denso plugs have a U-groove in the tongue and the NGK plugs do not. The U-groove is supposed to improve ignition of the air-fuel mixture if you believe the Denso propaganda.

Groove shmoove, i want the platinum bit on the ground electrode so i don't have to change them for another 60,000 miles. the ix iridiums don't have it but the regular iridiums do.
