Default 1991 Air intake system

Does anyone know any type of air intake system that has an air duct to fit on a TPI with an aftermarket BBK 58mm throttle body. The stock air duct is too small and I need a new one. Also does anyone know of an oval tapered filter that will fit on the end of the throttle body? Thanks

Not sure if this would work on a 58mm but you can try heating the accordion intake tube with a heat gun or by boiling to make it pliable enough to stretch. The next step would be to modify a traffic cone (not kidding - it has been done).

Good luck.
