Cars (2006)
In Cars, the tuners are causing havoc on the highway when they come across Mack, a tired hauler that is transporting Lightning McQueen to the Los Angeles International Speedway. DJ plays music to cause Mack to fall asleep, while Boost and Wingo push him back and forth. Meanwhile, a bobblehead falls onto the trigger that opens the trailer, causing the back door to open. Snot Rod sneezes, which scares Mack, causing McQueen to fall out of his trailer. Towards the end of the film, they are caught speeding through Radiator Springs, and are impounded and sentenced to pull Bessie.

Cars: The Video Game (2006)
They are the secondary antagonists in Cars: The Video Game as they are hired by Chick Hicks to steal gear out of Lightning's trailer. To do so, DJ drives in front of Mack and plays music to put him to sleep, while Snot Rod holds a ramp behind Mack, so that Boost can jump onto the roof to open the trailer. Finally, Wingo collects five boxes of McQueen's gear, while avoiding other objects that fall out of the trailer. After McQueen hears the news, he immediately races out to the highway, and steals the gear back from them. They are then arrested by Sheriff, where they confess to being hired by Chick.

Mater Saves Christmas (2009 book)
They are later seen in the Christmas book Mater Saves Christmas where they and Chick were responsible for stealing all the fuel in Radiator Springs as part of Chick's plan to use the flying fuel to win the Piston Cup and they kidnap Luigi and Guido but failed when they were stopped by Mater and his friends.

Trivia

 * Despite being the secondary antagonists, they have a very small amount of screen time. However, if it wasn't for them messing around with Mack, Lightning would have never ended up in Radiator Springs.
