I did the throttle body coolant bypass mod on my car using a 90* bended hose that goes directly to the heater valve. The only thing I don't like though is that it runs right by the wiring to the TPS and IAC. In fact, the TPS wiring is rubbing on it, so I covered up the TPS wirng with plastic conduit but I doubt that provides any real heat protection. What did you guys do to solve this? Or did you guys just leave it as is?

 

Not use an elbow....copper pipe....

 

I ran a 90* brass fitting in the intake and a slight "S" shape hose (i guess its more just offset than anything) but its not that close to my wires and I'm not worried about it.

 

Look closely.

 

The temp of the heater hose will not damage the TPS wires. But putting a cover on the wires to prevent them from rubbing is a good idea. You will be fine until you find a hose that's got a more ideal bend to it.

 

I used one of the heater core hoses with a slight S shape to it. Worked perfectly and I remember running into what you are running into.
