1. Disconnect the mass air sensor and external air temperature sensor (if necessary)    

2. Loosen the hose clamp on the intake at the throttle body.

3. Remove the bolt that holds the air cleaner.    

4. Detach the IAC (idle air control) and PCV (positive crankcase ventilation) lines from the side of the intake tube as shown.    

5. Remove the air intake assembly.    

6. Loosen the hose clamp that connects the intake tube to the mass air sensor.    

7. Remove the air temperature sensor from the intake tube (if necessary).

8. Remove the four bolts that hold the mass air sensor onto the air cleaner and remove the mass air sensor.

K&N intake installation:

1. Install the trim seal onto the heat shield. You might need to trim the ends of it to get the fit right.    

2. Connect the mass air sensor to the heat shield and filter adapter, using a gasket on each side of the heat shield. The two brackets should bolt on the shield side with the two longer bolts.    

3. Attach the silicon step down adapter to the upper end of the K&N intake tube using the provided hose clamp.    

4. Attach the silicon straight fitting to the lower end of the K&N intake tube using the provided hose clamp.

5. Attach the two provided hose ends with their respective hose clamps.

6. On models with an external air temperature sensor, drill a hole with an 11/16” drill bit at the marking on the intake tube and insert the provided rubber grommet and air temperature sensor. It should be a tight fit.    

7. Attach the K&N intake tube to the mass airflow sensor using the provided hose clamp.     

8. Connect the air filter to the attachment using the provided hose clamp    

9. Install the intake assembly and secure the bracket to the threaded stud with the provided nut.    

10. Attach the silicon step down hose to the throttle body using the provided hose clamp.    

11. Install the PCV line and the IAC line to their respective hoses from the previous step.    

12. Reconnect the mass airflow sensor and air temperature sensor electrical connections.    

13. Place the CARB exemption sticker visibly on the heat shield.

14. Verify that all connections are tight and start the vehicle.
