This is a brand new replacement bypass valve for the m62 supercharger on the Cobalt SS / Ion Redline.
This part supersedes the old part number with the set screw. The set screw is not needed and this will install perfectly in place.
We now carry a billet version of the LSJ bypass valve, found here.
For the 04-07 LSJ 2.0 liter with the M62 supercharger.
