Review on 🚀 Enhance Engine Performance with Genuine GM 215-603 Secondary Air Injection Pump and Bracket by Shawn Quick

Installed in 2008 Chevy Cobalt LS. A little difficult to install; Took me about half a day (including installing the valve). If water is dripping from the old pump, be sure to replace the air supply valve with it, otherwise it will be the same as the old one. Also clean the hose to remove any remaining water from it before installing the new pump. You may also need to replace the 40A fuse in the fuse box. It is recommended to use dielectric grease on electrical connectors and anti-seize thread grease on screws.
