Chris_Formula, that looks really good and clean. Looks nearly factory too. I am looking at some different ideas at getting more cold air on my Firebird.

Completed my new cold air intake to adress the larger breathing capability.
Maybe its interesting for someone.
3,5“ piping, k&n filter, metal housing with plexi glas plate on top.

Gets isolated air coming from the fender (light shining through).
Was at 93kpa @4000rpm with factory air filter assembly, now its at 99kpa.

I want to make one of these cold air intakes as well. This will be for my LS427/570, Tremec T56 Magnum F swap project, 1987 IROC Z.

How about some construction details, Chris?
