completely from the vehicle. The vehicle will still
be equipped with the horn located inside of the
fender.

fitting into the threaded hole on the supplied
Ø3.5" x 90° plastic inlet elbow.

secure with four 1/4-20 x 1/2" SHCS. Install the
air filter onto the flange on the inside of the air
box.

onto the air box and secure with 1/4-20 x 1/2"

elbow to the supercharger and flex hose. Secure
both ends with the provided hose clamps. (See
