Description

Bully Dog’s performance intake manifold features smoother contours and larger ports, greatly improving airflow and providing even distribution of the air/fuel mixture to each cylinder. The performance intake manifold is a replacement to the factory 2250 Cummins ISX manifold. Increase horsepower, torque, and efficiency to give your rig the performance it needs to tackle any challenge. As with all of our exhaust manifolds, all of the design, casting, and machining is done in the USA.
