[Healeys] old problem of cockpit heat

It may not hurt, but it probably won't measurably help either. If there were more room around the existing 4" (?) duct, insulating it with about 1/2" closed cell rubber insulation might produce measurable results.Given the lack of space around the 4" duct, perhaps wrapping 1/2" closed cell rubber insulation around a 3" diameter duct might work well. The air flow thru the 3" duct might not be reduced much & it should be much closer to ambient temperature.

 buy a second set of ducts, slice them length wise and slip over with the slice hidden under the fenders.. can't hurt?

Consequently I have been running with the intake closed. 
  I checked the cold air hose to make sure it is properly connected at both ends so as not to pick up heat from the engine compartment. Hose appears to be intact. 
  I have been thinking about getting a 3 inch hose wrapping it in insulating tape and put it inside the existing cold air hose. 
  Any thoughts or suggestions?
