Ok for the people not doing an open cone, here is an idea i got from another write up. use a roof vent seal to make a heat shield or to seal the filter into the fender.
Lowes and HD both have them.
here is a pic of the intake i made for my DOHC
another version i had before made installing a bit easier here are its pics
i mark it as PVC pipe but you can use any type. ABS, Steel, Al, cheese... well maybe not cheese. but you get the idea. the flex elbows came off my DOHC and they are on the 3100's i got an extra one from the junk yard for almost nothing.... and it has a port in there for the IAT as well.
