COMP Cams Thumpr NSR camshafts for 2011–2014 Ford 5.0L Coyote produce the Thumpr sound and enhanced midrange character for street-oriented builds. These cams are designed to use the Mustang firing order; to install them on an F-150 the engine’s firing order must be changed from the truck pattern to the Mustang pattern. The set targets drivers seeking the Thumpr note on compatible 5.0L Coyote engines.
