    FZR SVHO plugs are colder-when should modified SHO engines go colder?

    Just did a part search to buy the new '14 SVHO pump nozzle and noticed the online microfiche for the SVHO lists Ngk Lfr7a. as the stock plug. Previous SHO engines spec a heat range of 6. Is this because of the higher boost? I know the compression ratio is listed as the same as the old SHO. Just wondering if it was recommended to go a heat range colder on bigger supercharger wheels 13lbs+?
