This is a relatively inexpensive modification which may increase air flow into the throttle body. If nothing else, It makes a cool sound.

Disclaimer: I made this mod to my truck of my own free will. If you make the mod and screw something up, don't blame me. Also, this mod was not my idea. I found out about it by reading an invaluable forum. I simply put pictures with instructions I gathered from the F-150 Online message board f150online.com. This modification may void your warranty. If in doubt, check with Ford or your local dealer. Perform this at your own risk.

1. Disconnect the positive battery cable (this will reset the computer to adjust for any increase in air flow which may result from this modification). You will need a 8mm wrench for this.

2. Remove the throttle body cover by removing the three 10mm bolts. (One on passenger side and two on the drivers side of throttle body. Drivers side seen here)

3. Loosen the clamp holding the silencer assembly to the throttle body.
