I kno the HHR kit has been released, Is the airbox the only reason why it isnt out for the balts? What if you bought Hahns intake why couldnt they install the kit on the cobalts. Or could they?

 

1. It's not released yet.

2. Hahn's intake, because it's aftermarket, would not be warrantied, not like GM's intake. The whole reason to go with GM's kit is the warranty.

I believe part of the reason for the Cobalt was some tweaking needed on the tuning...
