Outer Limits 4x4 Board

Hi

Does any one know why the intake manifold on a TB42 is heated doesn't make sence as we use intercooler to cool the air why heat the intake. Can I block the hose that runs back to the thermostat houseing and join the two bottom hoses together or is there a reson for it.

These vehicles and engines are exported all over the world , the heating of the throttle body is to prevent ice up or sticking in cold climates . if your not ever going to see those conditions i suspect it would be fine to joint them but don't block them off as it may inhibit flow to other areas and create air pockets
