Classic cool DIY TBI cold air intake

After getting bored of this https://www.thirdgen.org/forums/tbi/...ir-intake.html I wanted a more classic TBI look.

Its made of a JY LO3 firebird/camaro housing, a taller TBI truck lid, http://www.summitracing.com/parts/SUM-G3000B/?rtype=10 cleaner base and fiberglass.

Someday I will get this http://www.summitracing.com/parts/SPE-9751/?rtype=10 to replace the improvised aluminium duct hose.

And of course it has the taller filter used in TBI trucks. (it has slightly more filtering surface then a 14x3")

Yes fiberglass. I sculpted the mold in "sagex" and brocke it out once covered with fiberglass.

No time for progress pics unfortunately.

Not really, I whanted the bowl shape towards the TB for effective air charge/flow.

Most bowl shaped ones, still go straight down the last 1/2 in, basically the same as the summitracing flat base center I used. I would probably replace it with a perfect bowl if I find one.
