Redline TV did a show with an 06 Cobalt LS (2.2 w/SAI -- didn't show what they did with the SAI tube) where they added the Injen intake and GMPP performance exhaust. Dynos that they did on the show gave 8 HP for the GMPP exhaust and 7 HP for the intake.ive heard like 11hp is that true?
No, the GMPP performance intake (I have and like -- $276 thorugh CED) does not have a connection for the SAI. Strange isn't it? It is listed for all L61 2.2 and LE5 2.4 models without SAI (RPO codes NU1 and NU6).its basically all in preference because they all do the same thing. does the gm intake have a spot for the SAI on certain models?
