Upgradeing Your Air Flow Sensor
You get the flapper type airflow sensor off the rx-7. Then you go to a junk
yard and cut the wiring harness off one (rx-7). You get the wiring diagram
from ford and Mazda for the wiring. Then you pop the black plastic cap off
thr rx-7 sensor and increase the fuel flow to the motor which in turn allows
the vehicle to have headers on it without forced induction or nitrous. Turn
the gear under the plastic cap (I believe two teeth) counterclockwise. That
increases fuel flow. I believe it’s an 89 rx-7

This is a Pic Brian M's intake mod.  It is on a 96 PGT and the only thing you need was a intake cone filter from American Products Company (www.4apc.net) Part number 15.1098.  All you have to do it take out your air box and plug the cone right into the Mass Air Flow Sensor.  then tighten the screws and you done.  Except that you mush rig up a brace that holds the sensor , kinda like the one on the right
