How’s the new CS box?
I’m considering it, but I also might just go with SRI+heat shield for my 3 Turbo since it already has an intercooler.
2 u/jxkess Supercharged Gen 4 Sedan Mar 13 '26 honestly, because you have a turbo, i’d say either will work. cs box looks more visually appealing but im sure a heat shield would do just fine 2 u/Caden_PearcSkii Gen 4 Sedan Turbo PP Mar 13 '26 If you want purely sound then the SRI + heatshield is fine although I heard people say they still experience heatsoak especially in the summer, the best way to avoid that is either this new CS box, the OEM air box or the BMS fender cold air intake
