5. On one end of the supplied LPE duct
(PN:XX05312-0004), there should be a label
that shows which end of the duct should be
connected to the throttle body. Make sure that
this end gets connected to the throttle body as
the duct will not fit correctly with the other end
going towards the throttle body.
6. Using silicone lubricant and a hook tool,
slide the 4” x 2.25” silicone hose (PN: XX05312-
0005) onto the new air duct (PN: XX005312-
0004), and then onto the airbox. Make sure that
hose adequately engages the duct and airbox
so that they can be secured using worm clamps
later in the installation.
CAUTION: Silicone lubricant should be used
sparingly. Avoid spraying silicone lubricant in
close proximity of any sensor.
