On a 2001 Ford Ranger 3.0L V6, In its infinite wisdom ford decided to pump hot water through the intake. I am assuming its to help emmisions, faster warm ups and even to prevent throttle body icing in colder climates is also a reason. I immediatly bypassed that as soon as a I realized I had on my hands, but could I run cold water through there and make a sort of Naturally aspirated water/air intercooler, or at least a mildly less warm intake. i've got access to free oil coolers etc. the pump is the hardest part. But i am sure i could find a fuel pump cheap that could handle continuous duty.
