I am in the process of selling my 2003 Ford F-250 6.0L Powerstroke diesel truck to buy a Scion xB. I was just wondering if the proformance parts you can get from the factory are any good? Anything input will help.

 

just go get everything aftermarket..save money, more choices

 

How do I know what will void the warrenty or not.

 

The only parts that are affected on warrenty by installing aftermarket parts are the ones you take off the vehicle to replace.....at least thats what my dealer told me

 

Other than that I have all the TRD parts and enjoy them, they make it a fun vehicle to drive.
