I was thinking about adding an oil cooler to my SVT. So, tonight I pulled off the shroud behind the front bumper and started checking things out. I noticed there's an adapter between the block and oil filter with lines running out of it. I traced one line up to the water pump and the other ran somewhere behind the engine. Is this some type of an oil cooling system? Can anyone tell me exactly where the lines run? Also, if this is an oil cooling system, would an aftermarket cooler be any better?

Thanks
