If you own a Cummins engine and aim to boost the flow to your upgraded T4 turbo, enhance overall flow, and lower exhaust gas temperatures (EGT's), then this Smeding High Ductile Iron steel manifold is your top - choice. It offers high strength, excellent flow, and top - notch quality. OEM manifolds are well - known for being restrictive and tend to shrink under heavy loads over time. These Smeding units are built to ensure long - lasting performance for your Cummins!
Part Number: SMED - 2ND.T4.3PC
Features
- T4 Mounting Flange
- Higher Flow Than OEM
- 3 Piece Iron 2nd Gen Location
Notes
- This manifold is for the 24V Cummins. It won't fit 12V Cummins without modification.

Using this manifold is quite straightforward. First, make sure your Dodge Ram with a 5.9L or 6.7L Cummins engine from 1998.5 - 2020 is turned off and cooled down. Then, remove the old OEM manifold carefully and install this Smeding 3 - piece manifold in its place. Ensure all connections are tight and secure. As for notes, remember this manifold is designed for 24V Cummins engines. If you have a 12V Cummins, you'll need to modify it for a proper fit. For maintenance, it's a good idea to check the connections periodically, especially after long drives or heavy - load use. Also, keep an eye on the flow and EGTs to ensure the manifold is performing as expected. With proper use and care, this high - quality manifold will serve you well for a long time.
