I just purchased the Denso IKH20 which is one step colder than stock and it is irridium. I plan to pump 40+/- WHP more than stock and by this spring I will probably use nitrous (guys have told me irridium and nitrous are fine). Is this a good choice? Is the colder a better idea?

www.sparkplugs.com the Densos were a bit pricey so I emailed them and asked if I could switch to Irridium NGKs (their 7, Densos are 12). As long it is NGK/Denso and irridium I'll be happy. If they ship what I ordered no biggie and if they can change it, I'll be saving some cash.
