Rotomaster M1040204N Turbocharger Cartridge

Rotomaster New Turbocharger Cartridge M1040204N

Rotomaster M1040204N is a new turbocharger cartridge built for direct OE-style replacement when the turbocharger core has failed but the housings can be reused. It uses journal bearing construction with coolant cooling and O.E.-grade components to support reliable turbo repair on select Buick, Cadillac, Chevrolet, and GMC applications.
