leg of the new Air Intake Bracket with the original Air
Cleaner’s rear mounting hole. Mark this location on the
Air Intake Bracket. Remove the Air Intake Bracket and
drill a 5/16” diameter hole in the marked location on
the Air Intake Bracket. Note: It might be necessary to
mock up the Stainless Steel Air Tube, Cast Aluminum
Air Tube, & Silicone Adapters in order to position the
Air Intake Bracket correctly.

in the Air Intake Bracket and against the flat spot on
the inner fender panel. Mark the location and drill a

on the inner fender panel.
NOTE: In some instances,
the support bracket may need to be slightly bent to
align with the fender panel correctly.
7. Attach the Mass Airflow Sensor & rubber gasket
removed in Step 3 to the back of the Air Intake Bracket
using (4) of the ¼” bolts and nuts provided.
8. If the vehicle is installed with a charcoal canister, install
the Nylon 3/8” Barbed x ½” NPS Fitting into the

with the 5/8” Hose Clamp provided.
