Do you remember the rubber adapter rings you had to install on the TB and the MAF to connect to the ESS rubber intake tube?
With 330 you don't need them because everything from the airbox output is about 10mm bigger.
oh oh!! I never installed such a thing!! Could explain air leak and erratic idle!!??? I just had those silver circular connectors you tighten over the ruber intake tube! Haha you learn something new everyday

Is it not possible to use these adapter rings on the air box side and use the 325 maf and air box and on the supercharger side I already have the 3.0L throttle body?
