Mass Air Flow meter: Get a MAF calibrated for the injector size you are using. If you are using an aftermarket recalibrated MAF and are also installing larger injectors, keep in mind this can cause problems with ignition timing (leading to part throttle detonation) along with some drivability problems.
MAF mounting hardware: MAF bracket, 3 MAF mounting screws, and 2 sheet metal screws to mount the bracket to the shock tower.
MAF power/signal harness: This is the MAF connector, 4 wires that go to the EEC computer, and EEC-IV connector pins for two of the wires.
MAF Air tubes: These are the tubes which go between MAF meter and engine and MAF meter and air filter box plus the clamps.
(Optional): Three EEC-IV pins and wire to hook up VSS and FPM2 signals.
