PARTS INCLUDED:
TOOLS & SUPPLIES REQUIRED:
1. JCW Only: Cut wire tie at valve cover breather hose to OE
turbo inlet hose. Pull out breather hose and remove rubber
collar. Then proceed to step #3.
6. Remove T25 TORX screw located on passenger side of air
filter box and lift off. NOTE: There are [3] pin mounts that are
pushed into rubber grommet mounts on intake manifold, so
effort may be required to lift air filter box off of mounts.

Disconnect fresh air pipe by rotating the 90° connection
counter clockwise and pulling pipe away from air filter box.
Remove air filter box from vehicle.
