Open hood all the way, use red button to lift to second position.

Remove screw on top of the front of airbox that connects it to the 90 degree bend

Disconnect 90 degree bend and move pipe out of the way (or remove it completely)

Locate 2 torx bolts at rear of airbox, unscrew them

Disconnect ECU (2 connections, pull tab out then remove)

Disconnect MAF (Mass Air Flow)

Remove vacuum line at rear of airbox (push round tab in and pull up)

Using long piers, reach down from beind the airbox and find the tabs on the pressure clamp. Squeeze them together and pull the clamp up and disconnect the hose, release and leave the clamp connected the the hose from the airbox.

Push airbox to rear of car. There are 2 tabs near the front that slip into rubber grommets, these need to be pushed back to slide out of the grommets and free the air box. Wiggle the airbox a lot if its stuck, typically the torx bolts fall back into the holes and prevent it from moving well, so lift the airbox slightly at the back to free these (since you cannot remove them completely from the airbox)

Once the airbox is free, disconnect the rubber hose on it and the sensor at the front and remove from the car.

Remove 3 torx screws from the rear of the airbox, separating the hose from the airbox and freeing the MAF

Replace the MAF, reinstall the 3 screws, and remove the pressure clamp.

Hand-tighten a screw-style clamp on the hose from the airbox. Hand tighten only to keep it in place, too tight and the hose will not slip on.

Reattach front sensor and rubber hose to airbox

Slip airbox back into car, lining up hose to slip on and tabs on airbox into rubber grommets. This is far easier with 2 people.

Tighten screw style clamp using long flex drive, should be able to squeeze it between ECU and firewall to get at the clamp

Tighten torx bolts at rear of air-box

Reattach 90 degree bend and torx screw

Reinstall vacuum line

Connect MAF and ECU

Close hood
