Stock Spark Plugs - heat range?

Looking at the stock plugs (Denso FXE24HR11), they are a "24" heat range (equivalent to an NGK "8" heat range). Any idea why our NA V6 has such cold plugs

Default Stock Spark Plugs - heat range?

Looking at the stock plugs (Denso FXE24HR11), they are a "24" heat range (equivalent to an NGK "8" heat range). Any idea why our NA V6 has such cold plugs stock? From my research the GT-R has basically the same plug specs (heat range 8) but a different tip/electrode.

I'm just used to heat range 6 plugs in N/A V6's. I know the VQ35HR uses the same plugs, except 1 range hotter. I can't imagine having to run a "10" heat range plug with 200 hp over stock; that's not streetable at all.
