The hood lift is caused by built up air pressure underneath the hood. Hood pins are one option. The other is to add the louvered plastic belly pan Ford added to the 2010s. The part goes from the radiator support to the front of the K frame. Per Ford, this part, plus widening the cover that goes forward to the bumper, reduce aerodynamic drag by 7% and help balance front end lift. The bumper cover will not fit the ’05 – ’09 without a fair amount of work. The louvered shield however is a 15 minute install. High speed hood lift is reduced because the louvered shield creates a low pressure zone and helps evacuate some of the underhood air. A bonus is potentially improved gas mileage.
The rear of the shield has plastic mounts that snap into existing holes in the K frame. The screws (5.5mm or 7/32” socket) can be backed out so that the shield can be removed. Inboard of these screws are two bolt holes. These are to clear the steering rack mounting bolts. My ’07 did not have the square holes in the radiator support to accept the factory metal mounting clips for the front holes on the shield. With the rear mounts in, I was able to line up the front holes and drill pilot holes for self tapping fender screws. While I put in screws, others have said just putting the two tabs on the front of the shield between the metal radiator support and the front bumper cover is adequate.
The shield has to be removed for access to the oil filter on the V8. After finishing your oil change, when you screw in the two rear screws back into the plastic mounts be sure to push up on the shield at the same time. This prevents the mounts from just spinning around in the K frame when you tighten the screws.
The part number for what Ford calls a “heat shield” is AR3Z-6C038-A. I paid $62.65 at my local dealer. I used a couple of fender screws from my stockpile but these can be found at Home Depot, Lowes or auto parts stores. If your radiator support has the square holes, you can use the “inserts” (N801169-S900 -- two @ $1.87 each) and “screws” (W710564-S439 -- two @ $1.26 each).
