FULLTILT PERFORMANCE CUMMINS ISX INTAKE

The Full Tilt ’15-’24 ISX Intake Manifold is a direct replacement to the factory 2350 Cummins ISX manifold and Cummins X15 manifold, fitting any 2015 and newer ISX motors. The inside has been completely redesigned improving not only airflow, but velocity and distribution of clean air into the engine. Our on-the-road testing has shown a strong .3-.5 MPG gain over stock with a noticeable change in engine power and responsiveness. This manifold will come painted Cummins Red, but can be ordered ceramic coated. As with all of our exhaust manifolds, all of the design, casting, and machining is done in the USA.
