"Free" Part #21 is a collectable free part featured in Need for Speed (2015) that can be collected at any time. Acquiring the part from the parked Ford F-150 will reward the player with a set of Street Style Wide Fender visual customisation parts for the Dodge Challenger SRT8 (2014), and it can be found in their garage inbox. The part can not be reacquired from a truck once claimed, and it can not be fitted to another car after it has been installed.
