depends on the company selling them. I bought my intercooler from a guy who had several, but was liquidating the inventory. ADC's intercooler is specific to your need, you might have to modify the intercooler a little, but that's part of the reason they are cheaper. ADC isn't selling the part, they are selling their service and R&D.
I also bought 4 garrett/kenne bell heat exchangers from a pawn shop for 125 for the lot...who knows how he got them, but he didn't really know what he had.
