I just had my supercharger ported and polished and the elbow was done along with the addition of a VMP 67 MM TB last year.Lots more air in so looking to replace the stock plugs and upgrade to NGK plugs. Am I right going with the NGK BR7IX plugs I hear great things about ? Im at 702wheels/730 tq now and going up from there but just looking to replace plugs. Your thoughts on these plugs? TY
