The NAPA Auto Care 150[1] is an ARCA Menards Series West stock car race held annually at Tri-City Raceway in West Richland, Washington.
The West Series first visited Tri-City in 1968, when Ray Elder drove his 1967 Dodge to victory.
The West Series visited Tri-City infrequently in the years that followed, with competitors like Jim Cook, Jack McCoy, Roy Smith, Dirk Stephens, Mike Chase and Jason Jefferson securing victories at the half-mile tri-oval.
In 2024, the race was added back and NAPA Auto Care became the title sponsor of the race that year.
[2] Tyler Reif is the defending winner of the race.
