More explanation on the electric tape:
The hard connection design of the charge pipe was to eliminating the accordian style rubber couplers that creates turbulence by interrupting airflow. this will require a gap of .025-.035 for an ease of install. the best and easiest solution was to use a plastic tape... electrical tape was choosen because of its availability in any store and the ideal temperature range (-40-+220 degree F).
also the use of tape as an easy and off the shelf seal is ideal because the gaps between the Envy pipe and the intake manifold is less than .035". a special seal could have been provided, but what happens when you accidentally tear the tape or it deteriorates over time and need a replacement? the use of electrical tape in the design is very ideal since it can be purchased realatively easy from anywhere.
