I have heard talk of air box mobs. What are they? How are they done? What is gained? Does it improve power and or MPG or hinder MPG.
Do these chips work as well as I am told? And do they improve or hinder also?

Thank You from the new kid in neiborhood

Black 98,
Use the search feature in this site in the "Engines" and "Other Drivetrain" forums. There you will find all the info you need including pictures. Use the keywords airbox mods.

Welcome to the site, this is the most informative, friendly (with very few exceptions) site on the web.

If you surf the different forums you will find more info on any modification possible to the F-150 truck.

Don't do any mod to your truck without checking here first, chances are somebody has done it and can help/guide you and what to do/not do.
