You need to be extremely careful when you start spewing Magnuson Moss. For all intents and purposes it's a pipe dream. It is more intended to deal with things like spark plugs, filters, etc that do not increase factory performance levels. If you add a CAI, exhaust, chip, etc that increases the performance levels set from the factory, you have now modified said vehicle to a different level than as delivered and they CAN and WILL void your warranty and refuse claims if they so choose. You will lose that argument if you pursue it and Ford fights it.
Let's say you make a widget that is designed to hold 1 gallon of fluid. All of your engineering and testing is done based on this capacity. After extensive testing and research, you find that the unit is perfectly safe and operates as designed holding this 1 gallon of fluid so you take it to market and sell the crap out of it because it is truly a remarkable widget and everyone wants one! Then somebody comes along and discovers that with a little work, money, and innovation they can make it hold 2 gallons of fluid and it truly is a remarkable widget in this form! Everybody wants in on the bandwagon because they all know that a widget that holds 2 gallons of fluid is truly better than one that just holds 1 gallon! But low and behold the 2 gallon widgets start to fail! The materials used to manufacture the widget was never designed to hold 2 gallons of fluid. So they start sending the widgets back to you to be warrantied and replaced for free. Are you obligated and responsible for replacement? NO!!! You never designed the widget to hold 2 gallons of fluid nor did you ever manufacture one that way and deliver it!!
Long story short...(too late)...if you increase the performance output of your car, it is no longer "as delivered" and Ford (or any manufacturer) has the right (and rightfully so) to deny your claim.
Bottom line...you play you pay.
