How to Install BBK 85mm Throttle Body on your Ram

STEP 1: Disconnect the negative battery terminal.

STEP 2: Disconnect the air temperature sensor plug and the throttle body control motor plug.  

STEP 3: Loosen the clamps on the air intake tube and air box, and then remove the tube.  

STEP 4: Remove the four bolts that secure the throttle body to the intake manifold.  

STEP 5: Remove the stock throttle body. The stock O-ring seal will be re-used. Be sure to wipe off and debris from the gasket.  

STEP 6: Bolt on the BBK Throttle Body using the stock hardware. On the 5.7L Hemi Plastic manifolds, take extra care when re-installing the mounting bolts. The “Speed Nut” type threaded nuts can be easily stripped. Make sure the threads of the bolts are properly engaged with the nut before tightening.  

STEP 7: Re-install the air inlet tube to the BBK Throttle Body and air box and then tighten the clamps.  

STEP 8: Re-connect the air temperature sensor and the throttle body control motor plug. Re-connect the negative battery terminal and refer to page 2 of the instruction sheet for throttle relearn procedure. ​

Gas pedal/Throttle Body idle relearn process

With the addition of the larger bore throttle body and its larger intake flap, the gas pedal and throttle body must be re-synched before starting the engine. This must be done to prevent a check engine light for “increased idle” The procedure is simple. 

After installation instructions are complete, please follow the procedures below. If throttle body has already been installed, please just follow steps 1- 4. 

1. Disconnect battery for 5 minutes. Reconnect. (or use a code reader to clear any stored codes in the computer)  

NOTE: If this is a new install, proceed to step 2.  

2. Turn ignition key to on position, do not start the engine.  

3. Slowly depress the gas pedal to the floor, and then slowly release it. Do this three (3) times. Turn the key off.  

4. Now start engine. The gas pedal is now in synch with the larger throttle body.
