Read up on warranty law, unless it causes a failure, changing parts does not void a warranty (Magnuson Moss?).How do we know if these will be warranty approved?
'I remember the day after I tuned my 2011 Mustang GT ford came out a Bulletin to dealers warning them to look for signs of Engine mods and tuning and VOID all claims and let the customer fight it out with them (as a result of a few bad tunes and knock sensors turned off in said tunes) ... Just remember they have deeper pockets and more lawyers than most folks so if they fight it won't be pretty... Just sayinWouldn't put a failure prone engine in a sporty car?????? Obviously you never owned a new 5.0. LOL!
Ford doesn't really care. You could have and after market cup holder and they would blame it on a tranny failure. They will do whatever they can to avoid warranty work.
