K&n
 

I was looking at other pics of Air boxes and noticed that my air box looks completly different from others.

It's an aluminium box w/a flap inside. One wiring connectors goes into it. Also the filter sez K&N on the front.

Is this factory or aftermarket?

86 base

aftermarket

the stock box is black made of plastic and says MAZDA on the top of it

Does the original box have a wire connector on it?

If not where did this one come from? It's in the wiring harness. Without it hooked up the car won't run.

Also it has some adjustment screws on it. What do they do?

oh shit wait the aluminum thing you described is the air flow meter sorry about not reading it right. You have the stock BOX but you have a K&N drop in filter the connector is supposssed to be there.
