I talked to my tuner yesterday and he advied me to run NGK TR6 in the ls2, The TR55 is the same plug in the LS1 that has a lower compression ratio, The LS2 runs better with the TR6 due it's higher compression ratio

in the ngk line, one heat range colder is tr6ix. funny thing is do you do a search on ac delco site, it calls for the same plug for z6 as c6zo6 but on ngk site, it calls for tr5ix for the c6 and tr6ix for the c6zo6...so, is it really one whole heat range cooler then? ngk only have the tr7ix which on ngk site, it is used for sts-v. where are the cheapest places for these ngk ix plugs?
