is the stock intercooler air to air, or air to water? also if it is air to air do i need air to water set up if I'm running 500hp?

 

Really? No No and NOOO

What the above folks are saying is that this is an extremely basic question (it's air-to-air) and they are worried that someone who cannot see the answer for themselves should not be thinking about building a 500-hp car. I'll go ahead and say that there are plenty of 500+ hp cars running air-to-air and lock the thread.
