Step 3: Disconnect the Crank Case Vent (CCV) hose at the back of the OE air box 3 .
Step 4: To remove the OE air box, pull the box straight up. Leave OE rubber grommets in place.
Step 5: Remove the M6 bolt that secures the intake housing mounting bracket to the inner fender well (Save the bolt as it will be reused) 4 .
Step 6: Carefully, remove the temp sensor from the OE intake tube by pulling and twisting straight out (Do not bend from side to side while removing the sensor).
