Step 4 - Remove valve cover breather tube from the air
tube. Using a small screwdriver, remove the grey retaining
clip from the Mass Air Flow (MAF) sensor connector.
Press tab and disconnect the MAF harness from the sensor.
Loosen the hose clamp closest to the airbox, remove the
air tube from the engine compartment. Place the factory
air tube and MAF assembly aside, it will be reinstalled
later.
Step 5 - Pull the coolant overflow tube from the retainer
on the air box and free the MAF wire loom from the
airbox. Pull straight upward “firmly” to remove airbox.
You will feel resistance, however the airbox should pull
out without removing any fasteners.
Step 6 - In the void where the airbox was, you will see a
fastener with a T-30 Torx head, remove this fastener. This
will serve as a mounting stud for the air box in a later
step.
Step 7 - Remove one of the black rubber grommets from
the bottom of the stock airbox. Insert this grommet into
the hole on the inner fenderwell as shown, with flat side
out.
This image shows the grommet installed in the new
location and the Torx head stud (removed in the previous
step) that will be inserted into the grommet in a later step.
