hmm debate debate.... do you have one of these on yours? whoops i mean 2 of these

 

I don't have them, no.. The entire kit is jet hot coated, and on one side the turbine housing is practically touching the plastic horn, and has never gotten hot enough to melt it one bit..

If I had a single setup sitting right in front of my radiator I would probably just do the coating and stick a shield on it.
