C. Attach the supplied 90
° compression fitting
onto the non-flared end of the 5/8” tube and
secure (the fitting should be tightened with the
pipe thread end pointing toward the front of
the vehicle).
D. Following the Air Injection Modification diagram,
cut a 2” length from the 5/8” end of the supplied
180
° rubber adapter. Place the short length of
hose onto the discharge side of the factory air
pump. Into this short hose, insert the supplied
5/8” tee with the leg pointing up. Slide the 5/8”
end of the180
° rubber hose onto the horizontal
run of the tee. Attach the 90 ° end of the supplied
5/8” x 90
° x 48” rubber hose onto the leg
(pointing up) of the plastic tee and route the
straight end in between the front of the core and
the exhaust air injection location (see photo -
12). Use the supplied 5/8” hose barb union to
connect the new 5/8” hose to the existing hose
running to the passenger side exhaust manifold.
Trim hose length to fit.
E. Using the supplied 2-3/4” sleeves and #44
hose clamps, connect the 2-3/4” tube to the
discharge of the supercharger and the
aftercooler core inlet. Leave the clamps loose
temporarily.
F. Remove 1” from the round end of the original
Vortech aluminum throttle body elbow and re-
install onto the throttle body using the original
clamps and sleeves. See Aluminum Discharge
Tube Modification diagram.
G. Install the remaining supplied heat sleeve/blanket
onto the supplied 3” discharge tube. Using the
supplied reducers and hose clamps, secure the
tube to the aftercooler and the modified throttle
body inlet elbow. Attach the existing super-
charger bypass valve and supplied 1” x 4” hose
to the bung on the 3” tube and secure with the
existing #16 clamps.
