Frost King vs DEI Gold Wrap

Airbox Insulating Wrap Test

During the airbox intake air temperature testing it became apparent that most intakes perform about the same when it comes to delivering “cold” air to the turbocharger – poorly.

The topic of wrap on an intake occasionally comes up as a way to keep those temperatures down.  Gold foil wrap is the go-to product when thinking about this type of project, but my past experience with reflective foil wraps didn’t leave me impressed.

This test is to see if the pre-turbo intake temperatures can be lowered by using a thicker insulating material.  The product selected is an inch in thickness, foil backed, and has an R value of 4.

Behold the Frost King intake:

Wrapped inside the Frost King pipe wrap insulation is an Eventuri intake.

Frost King (26 mm thick) laughs at the puny DEI Gold Foil (0.26 mm thick)

Testing of this intake “mod” will be the same as has been done during the prior intake temperature testing.
