REMOVAL OF THE FACTORY AIR BOX
1. Disconnect the battery.
2. Disconnect MAF sensor connection; (Figure #1)
a. The MAF plug on the intake hose. Push down on the small tab on the harness side and
gently pull the plug out. Do not pry or damage will occur.
3. Loosen the hose clamp connecting the MAF housing to the turbo inlet hose. (Figure #1)
4. Remove the (2) T-27 screws connecting the MAF housing to the factory intake box.
5. Mark the MAF sensor so it is reinstalled in same flow direction.
6. Remove the MAF housing from the factory air box. Set the MAF housing aside in a safe place.
The sensor is delicate.
7. Remove the (3) T-25 screws holding the factory intake box cover to the factory base.(Figure #3)
8. Remove the air box cover and the factory air cleaner element.
9. Fully loosen (1) T-25 screw on the RS (passenger side) of the air box that connects the air box
base to the engine.
10. Pull the air box base straight up to disconnect it from the engine. It will take some effort to
disengage the base from the interference fit rubber grommets but do not pry on it. Human force is
sufficient. Once the base is free, rotate it approximately 1/8 to 1/4 turn towards the rear of the car
while at the same time pulling it apart from the factory fresh air pipe. If the grommets come free
from the intake manifold reinstall them now. They are need to mount the new MAXX-FLO™.

11. (OPTIONAL) Remove the factory fresh air intake hose from the front inlet attachment on the
radiator support. With a flathead screwdriver, release the intake hose from the bezel in the front of
the car (near the headlight). When the hose is disconnected, remove it from the car by twisting it
counter-clockwise out of place. You will no longer need this hose. NOTE: It is recommended you
keep all the factory parts to reinstall at a later date if needed.
