I would just stick to NGK Platinums granted they don't last as long as Iridiums, but I rather change my platinums more often. It it that hard and its cheaper as well. I rather change out platinums every 12,000 miles then an iridium every ??? miles. By the way what is the recommend time for Iridiums?
Platinums are cheaper too. 
Iridiums can go 100k, but denso reccomends 50K on a performance car. I don't think they cost that much more over platinums for the added performance they give, but I think you could see similar results with a $2 NGK copper and change plugs every 20-25K. This is very easy on a an I4 Honda. The only reason I would get Iridiums is if I was a V6 owner cause those 3 plugs in the back are a biatch to get too and changing them often would suck.
