Disconnect clips holding the air filter housing onto the base. Also, remove the connection or clips securing the mass airflow sensor to the lower intake hose.

  • Remove the air intake hose from the throttle body

The moment the other air intake hoses have been loosened, you will be needed to take the air intake hose connection off away from the throttle body. Normally, this connection is secured by a hose clamp. Make loose the hose clamp until the intake hose slips off the outer lip of the throttle body.

  • Remove complete air intake housing from the vehicle

The moment all connections are loose, you will require removing the whole air intake housing from the engine compartment. Put it aside for now, but have it handy since you will be needed to reinstall it after the throttle body has been cleaned.

  • Replace the air filter
