Ok I know this thing does no good but do you think it has damaged my motor?

This was on the truck I just bought, the owner didnt say how long it has been on there and i did not see it when I was looking at the truck because it was tucked under the air box.

I am going to take it off immediately but my question is do you guys think it could of done any damage?

The truck runs good and doesnt make any abnormal noises or anything

More then likely its just an ICP mod... Where is it wired to?

I see no reason to remove it right now, better to have gauges, but its only an ICP mod.

Huh? Its wired to the intake air temp? If its wired to the intake air temp then its not doing a damn thing, because the PCM will not change anything based on the intake air temp.

Post a picture of what its wired to.

There is no Idle Air Control on a 7.3... Which is why I asked the question...

There is an ICP sensor, which is where that box is more then likely wired to, there is an intake air temp sensor (does nothing) and that's about it... There is really nothing else that box could go to, unless its running an EBPV (Exhaust Back Pressure Valve) exhaust brake.

Need a pic of where that box is wired to to tell you for sure.

PCM most definitely makes changes due to IAT. This sensor is why you get worse MPGs in the winter vs summer. It is used to help determine the fuel tables for colder air (more oxygen since our trucks don't have 02 sensors to determine this).
