17803229 - Stage 2 Performance Upgrade Kit

Make that 2005-2007 Cobalt SS/SC sit up and beg with our Stage 2 Performance Kit. Building on the success of our Stage 1 Kit, our Chevrolet Performance engineers wanted to push the over achieving four-banger just a little bit more. Stage 2 takes your Cobalt SS or ION Red Line from a stock rating of 205 horsepower all the way up to 241 horsepower. The key to making that power is increasing the boost on the factory supercharger by swapping out the stock blower pulley. Increased boost means more air getting pumped into the high-revving Ecotec, and the increased airflow requires more fuel. That’s why GM high-flow injectors are included in the kit. Together, this Performance Kit will keep your Cobalt/ION Red Line boosted ahead of the competition.

Kit Includes:

• High-flow injectors
• Supercharger pulley
• Correct length supercharger belt (P/N 12597993)
• PCM reprogramming

NOTE: Premium (93-octane) fuel is required for Stage 2.
