I've been pouring through these posts, web searches, and everything else. I have a 08 Dak, 4.7L Flex, AirAid CAI, AirAid throttle body spacer, Jet Stage 2 performance chip, dual Flowmaster exhaust. I'm coming up on my 30k service as well and the only plugs I've found are Bosch, Denso, or Pulstars. The orginial Bosch are nickle YYTrium plugs, and they have a comparable replacement. The bottom plugs are Iridiums. So, which plug is better? I don't want Denso, Pulstar, Champion, or NGK; so that leaves the rest. Also, if platinum isn't recommended; why are the websites etc. recommending them?
