Sorry Jon I put the wrap on at the same time as the building of the in take.
I'm not sure what your prototype intakes are made of but the PVC pipe also
helps with the slowing of the heat transfer. I'm going to rest test this
weekend. I rebuilt the cover around the air filter to block out most of the
air from the engine compartment. Keep in mind that the 2deg rise was when
moving and the heat from the eng. compartment was being blown through with
the movement.

Don,
Just out of curiosity, did you measure the temps before the wrap? It
would be interesting to see how much of a drop the insulation gave you.
The reason I ask is there are a couple of Daks now running around with
"Steiger Performance" prototype intakes, and in doing some testing
on a prototype cold air box, we noticed that the intake temp was only 2
degrees below ambient. We were pretty happy about that until we
pulled the airbox and discovered that the intake temps were now
a whopping 4 degrees above ambient! ;-) That was in ~50 degree weather
though, I have yet to test it in the summer heat, which I plan to do
soon. I have a hunch though that a cold air box isn't going to be
worth the expense. ?
