1986-1993 Ford Mustang 5.0
Cold Air Induction Systems
Part #s 1556 & 1557
Step 1 Remove entire stock air inlet system from vehicle, this is easily done by removing the
hose clamp at the throttle body, the two mass-air mounting bracket bolts from the strut
tower/inner fender well area, and the two filter box mounting nuts at the top edge of the
factory air box.
Step 2 Once this entire assembly is removed from the engine bay, the air box silencer (if not
previously removed) will be exposed. This is located inside the inner fender well
directly behind the air filter housing and is attached with three nuts which once
removed will allow the silencer to be dropped down to the bottom of the fender and
removed from under the vehicle. Also remove the two rubber air box mounts from the
fender well by simply turning counter clockwise and unthreading.
Step 3 Remove the mass-air sensor from the main assembly by simply unclamping it from the
stock inlet hoses. Once disassembled you can now remove the three bolts attaching
the bracket to the bottom side of the mass-air sensor. This bracket and the related
bolts will not be utilized in the installation of the BBK Cold Air Induction System.
Step 4 To finish installation simply install components in the vehicle as shown in Figure 1. For
Fender well-style kits install components as shown in Figure 2.
Step 5 Some models come with a large black grommet. Install as shown in diagram then
lightly oil the inside diameter to allow the 3-1/2” filter tube to slide through the grommet.
