matirial removal on 95 7afe intake manifold, more than just cosmetics Options

Not to be a debbie downer but you will see NO gain from this as most of the intakes on celicas are scavenging intake.(excludes turbo)

This means the intake plenum stores air inside that large opening and only draws more in when accelerating, so the intake is always pressurized.
ALSO very much like an exhaust the intake requires back pressure.

As for turbo application this was a smart thing to do as you will reduce drag when forcing that air in!


EDIT: If you are running an NA system and you do this you WILL cause your car to lean out, because you have no way of bumping the fuel up.
Its simple you want more air then you need more fuel!

I just used a spare to see what happens. Just a what if. Im curious if this would be effective with a stock air box, a short ram, or even a ram air. Ill do some investigation

You will have the most effect with a ram air as your forcing air in, any type of "forced" induction you will see a gain as you're literally cramming air in. You want as smooth of flow as you can with forced induction.
But with a ram air you're only forcing air in when you're moving, so at idle you will be running lean, not a bad issue but running a car lean can take a tole on your piston rings over time.
