How to install a BBK 56mm Throttle Body on your 1994-1998 Mustang

STEP 1 Disconnect negative cable

STEP 2 Disconnect the Throttle Position Sensor (TPS) electrical connector; the throttle cable(s) and the auxiliary return spring (if equipped) from the stock throttle body.

STEP 3 Unclamp and move aside the air filter inlet tube from the neck of the throttle body.

STEP 4 Unbolt four (4) nuts (or bolts) attaching the throttle body to the intake manifold and remove the throttle body from the vehicle.

STEP 5 Clean gasket surface on the intake manifold and install supplied throttle body base gasket. The manifold opening may be port-matched for optimum performance. Some models may require this for butterfly clearance when at part throttle.

STEP 6 Remove the TPS from the stock throttle body. If it is equipped with an IAC valve, use the supplied gasket to swap it over to the BBK throttle body. Install the TPS sensor on the BBK throttle body with stock screws.

STEP 7 Install BBK throttle body onto the intake manifold and reinstall the stock nuts, or new hardware if supplied.

STEP 8 Reconnect the electrical connections, throttle cable(s), return spring (if equipped) and inlet tube for the cold air.

STEP 9 Reconnect negative battery cable and start engine.
