    Trying to duct the back hole..

    I am attempting to run ducting to the back hole of the CSL airbox with non-factory parts. I see a route that I could pull fresh air. If you stick your hand in the fog light area to the right is the brake cooling duct, the top hole I have feeding my snorkel but to the left there is a "bulbous" part that I could envision cutting (opening) and somehow running tubing from that to the rear hole.
    In a previous post I made a while back jbfrancis3 explained how one could use this area to pull fresh air from and Obioban suggested I buy some 3" brake ducting to use as ducting.

    Today at the hardware store I picked up some black rubber pieces in the PVC fittings section thinking somehow someway I could make them work for me. Can anyone tell me if these will just melt without me having to ruin one with a heatgun experiment?

    Ducitng this hole looks quite tedious and tight, so very close to the alternator. I would love to duct that rear hole because currently while at idle it sucks in air 4" from the hot alternator. This seems like it will take a bunch a fiddling around, maybe I should simply source factory parts.
