3. Unplug the red quick release vacuum connector from the top of the intake manifold.  To do so, gently pry outward on the ends of the red u-shaped connector and push it outward, it should pop out and allow you to lift the connector off easily.

4. Unplug the sensor on the outside of the intake manifold by purshing down on the release tab and pulling outwards

5. Pop the wiring and vacuum line out of the keepers  to allow them to move more easily.

6. Using your trim tool, gently pry outward to remove the clips from the intake manifold holding down the wiring.

7. To disconnect the throttle body, gently move the red tab rearward (toward the wiring) to release it, and then push down on it to release the tab from the throttle body itself, and pull the wiring free.

8. Unbolt the support bracket at the top of the manifold using a 10mm socket.

9.  Take the small 13mm nut off toward the rear and bottom of the intake manifold.

10. Using a screwdriver or 8mm socket, undo the hose clamp holding the intake to the throttlebody.

11. Disconnect the wiring on top of the manifold.

12. Using a 10mm socket, remove the intake manifold bolts where they mount to the cylinder head.  You should be able to fit your socket and extension through the access holes in the manifold.

13.  With the bolts removed, there will be another vacuum line to remove from behind the intake manifold.  Reach your hand back and pop the retaining clips loose similar to the way you did with the red connector earlier.

    
    

14. There are two wiring connectors attached to the backside of the intake manifold as well, using your hand or a trim tool, gently pry them off of the manifold.

15. Remove the intake manifold from the engine bay.
    

16. Disconnect this line from the breather and set it aside for later.  To do so gently push in on the white tab

17. Use a heat gun to heat the ends of the factory pipes slightly and pull the fittings free.  Go in slow bursts with the heat gun to avoid ruining the fitting or the line in case you want to go back to stock at some point.  Alternatively if you don't care you can use a razor blade to carefully remove the fittings from the hoses without hurting you, yourself, your neighbor, your friend, etc.

18. You may need to gently push some of the wiring out of the way to get to the plate

19. Using an 8mm socket remove the factory breather plate from the car.
