If I were you I'd get rid of those iridium plugs (which can get really hot) and go to the dealer and pick up the stock NGKs (copper, much cooler spark). They have a double-electrode and they don't need to be gapped. If you MUST use the iridiums, then your best bet is to gap that at a minimum of .032 for 14PSI.

you really should get rid of the iridiums. buy NGK BPR7ES or NGK BP7ES. They are the same, but the second comes without the noise interference resistor so theyre cheaper. Gap them .030. When you start to run 18+ psi buy BPR6ES and gap at .028
