Up for sale, slightly used HAHN Intercooler for SKY Redline or Solstice GXP. But if you're good in fabricating and machine work, you might be able to modify this to fit your cobalt.

I'm selling it, since I'm going for a customized bigger IC for my engine build in a month.

Brand new, it's $900.

I'm selling mine for only $550 plus shipping.
