Follow these instructions carefully to ensure correct fitment and operation.

STEP 3

  • Disconnect the smaller plastic breather tube from the air inlet tube. You can leave the sound tube connected.​

STEP 4

  • Loosen the clamps on the air inlet tube at the air box and the throttle body. Remove the air inlet tube and set it aside.​

STEP 5

  • Remove the 4 mounting bolts from the stock throttle body, as you remove the stock throttle body; flip it to disconnect the motor plug on the bottom. 

STEP 6

  • Wipe off the stock rubber throttle body gasket to remove any oil or debris. You will be re-using this gasket.​

STEP 7

  • Connect the motor plug to the BBK Throttle Body. Using the throttle body spacer provided with O-Ring, install the spacer with the small opening towards the manifold and the large opening and O-Ring towards the BBK Throttle Body. Use the supplied hardware to secure the BBK Throttle Body and spacer to the manifold.

  • Re-install the air inlet tube and reconnect the breather tube. A little WD-40 or light grease on the inside of the tube may help in this process. Tighten Clamps.​
