Is there a gauge that measures air intake?
I thought it was a vacuum gauge but im not sure.
Its not for a turbo car, its for a N/A.

you can buy a vacuum gauge, but are rare, so you can just use the vacuum half of a cheap boost gauge. As far as i know, there is nothing available that can measure air intake( in terms of cubic feet per minute) on your car.

thats not bad, someone on here is selling a blitz vacuum guage for around $75.
How do you fit them and where do you plug them in?

Why do you want to measure air intake?
I assume it is for your Celica? Does it have AFM?
Digital Voltmeter on the one of the AFM pins will show how much cubic meters are coming in if you can calculate what is the ratio of Volts vs cubic meters (which is possible with measuring duty cycle of the injector on near stoich with working oxygen sensor).
But having vacuum gauge is pointless.
Vacuum gauge will not show flow directly. It will show same readings on 8L engine as 1L engine on full/partial/closed throttle.
