Bring charge air into Cummins ISX/ISX15 engines with this PDI Big Boss intake manifold. It replaces the intake-side passage that carries air from the charge-air plumbing into the engine, joining the incoming air connection to the engine’s intake ports.
The manifold forms the final part of the air route into the engine after the turbo and charge-air cooler. Its passages carry the incoming air to the intake side of the cylinder head. Choose the model-year range in this listing to match the engine’s connection and mounting arrangement.
