So this is the first block, simple packing tape to test effect on cooling... Results, no effect on cooling at all. Standard freeway running temp remained 197-201 F over a weeks' time. Baseline was the same. as reported by Torque via bluetooth OBDLink MX.
Unfortunatley, during these daily 45-52 mile commutes(oneway), there was no appreciable effect on FE. If there was an improvement it was < 1 mpg (us).
I also taped over the outer inlets on the bottom portion of the bumper inlet to the first vertical piece. pic to come l8r.
