I bought an adaptor/K&N 'style' kit off ebay for about $20.

ADAPTER AIR FILTER SUPRA 86-92 NA

It mounts to the AFM (just remove the factory air box, but save it, cause it costs $250 from Toyota).

I drove the car with just the K&N, sucking hot underhood air into engine. It seemed to have "lost" 10 hp.

I used galvanised sheet metal, and flat plastic (from a new kitchen trash can) to 'box in' the filter so as not to draw hot air into the intake, and to force fresh air in from behind the headlight.

You can use whatever, but that was quick, easy, and cheap.

Now, if I were doing it again, I'd see if I could find a small plastic rectangular trash bucket (right color for matching underhood stuff) that would fit even better.

Next........

I cut away the factory plastic wall to let some of the air coming into the front grill (where air goes to radiator) to also be forced into the area behind headlight so it would go into the big oval hole where the old factory rubber 'snorkle' was mounted to the factory air box.

After boxing the filter in, so it only gets outside air, it feels like it gained 10hp. I could FEEL the hp difference.
