Review on AEM 21 533P Polished Intake System by Jonathan Devarapalli

Perfect fit for 2.4L Ecotech and also comes with EO sticker. You will need to remove either the bumper corner or the passenger side fender. The 06 Cobalt SS requires the removal of an air hose which is a 10mm bolt and then a fairing retainer. Take them out and he comes out immediately. After that, the entrance fits perfectly. PVC hose not included. So you need a vacuum hose for it. The diameter of the valve cover varies from intake to intake. Everything else fits perfectly and you can definitely tell by a short plunger or even a stock shot.
