I heard the iroc has a better cold air induction system so i was wondering could i put the Iroc System in my GTA I heard it gave the Iroc 10 more hp over the GTA.Any info will help maybe some pictures too.Thanks

 

I don't think it will fit. The battery is on the opposite side in an IROC. I'm sure you can modify your existing air induction system to bring in cold air.
