Remove the entire stock air inlet system from your Mustang by simply unclamping at the throttle body and removing the bolt attaching the air box to the inner fender well area. Disconnect all hoses, wiring, etc., and then pull upwards firmly on the airbox to disengage from the rubber grommet in the framerail.
Note:Rubber grommets will sometimes stay attached to the bottom of the stock airbox, be sure to remove them and reinstall into the framerail.
Remove the mass-air sensor from the air filter box and attach to the new filter mount, using the supplied bolts and nuts, with the electrical plug portion at the top.
Note:On most models the airbox will need to be disassembled in order to allow access to the mass-air flow sensor. The airbox will come apart approximately 3 inches down from where the throttle body inlet hose attaches to the airbox.
Attached the 2 supplied grommet studs to the fender filter mount with supplied hardware. The studs must be facing downward to slip into the rubber grommets in the framerail.
Note:Some models come with a large rubber grommet and separate tube assembly. If so, install the large grommet into the corresponding hole in the fender well bracket. Lightly oil the grommet inside diameter and carefully slide the tube through the grommet.
Install the assembled filter mount into your Mustang by pressing the aluminum studs firmly into the grommets on the framerail then attach at the grommet on the inner fender well using stock the hardware.
Slide the appropriate sized tube coupler over the mass-air sensor and attach with the supplied hose clamp.
Slide the other tube coupler over the throttle body end of the inlet tube with supplied clamps and install between the throttle body and mass-air sensor. Align the tube while tightening the hose clamps. (On some models, the coupler attached to the mass-air sensor will be larger than the inlet tube. This coupler is designed to clamp down more than usual and will provide a smooth transition from the mass-air to the inlet tube.)
Attach all tubes, wiring, etc., to the new inlet tube (some models will have hoses supplied to adapt to the OEM hoses).
Install filter from under the fender and clamp tightly into position.
Note:Filter will not fit through the opening in the engine compartment, therefore it MUST be installed from underneath the fender.

These guys are great! Customer service is absolutely top notch. Their pricing points are spot on and every month they off some sort of special on multiple parts. Not only that but the staff will educate you on the parts and their customer reveiw option of every part has been a huge help in determining the validity of each part you buy. American Muscle is the perfect example of what a full service parts distributor and custom tuning shop should be. I'm just glad they are Mustang exclusive!
