How to install a BBK Cold Air Intake on your 1986-1993 Mustang

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.
