Phil Bonifield is an owner/driver in the NASCAR Craftsman Truck Series and Busch Series. He fielded Team Racing for six years in the Truck Series.

Bonifield began his racing career in 1973, when he began competing with BMX bicycles. Racing across the United States, he won several championships from 1979 to 1983. In 1987, he moved to go-karts, where he raced against Kevin Harvick and Casey Mears, before competing part-time in the NASCAR Elite Division Featherlite Southwest Series in 1991.

Bonifield became a driving instructor at the Buck Baker Racing School in 1993, after he moved to the Southeast from California. Around the same time, he opened his own fabrication shop, and worked for various Winston Cup teams. In 1998, Bonifield closed his fabrication shop and began fielding entries in the Truck series. His first race as owner in a points-paying event came that season at Walt Disney World Speedway in the No. 11 Red Line Oil Chevrolet, driven by Brett Bodine, who qualified 13th but finished 32nd after an engine failure. Bodine ran two more races for Bonifield that season, both races resulting in DNFs.

In 1999, he decided to pull double duty as an owner and driver, with Tom Mazucchi coming aboard as a partner in the No. 23 Red Line Oil truck. He made his Craftsman Truck Series debut at Evergreen Speedway, finishing 30th. Bonifield would compete 13 more times that year, and finished 31st in points, and 7th in Rookie of the Year standings. In 2000, he ran just eight races, and did not finish a single race.

In 2001, Bonifield posted a career-best 24th twice, at California and Las Vegas. That same season, he began running races part-time for Impact Motorsports, and purchased Impact's owner's points and equipment after it shut down, renaming his operation Team Racing. He also made his Busch debut at the MBNA Platinum 200 for Jay Robinson Racing, starting 34th but finishing 36th after engine problems plagued the team.
