Thumbnail Filmstrip of 1994-1998 5.9L 12V Cummins Ported Iron Exhaust Manifold AFE 46-40044-1 Images
The factory manifold restricts exhaust flow and slows spool. The aFe BladeRunner one-piece ductile iron manifold outflows it by 25% for better throttle response. It fits 1994-1998 Dodge Ram 2500 and 3500 with the 5.9L 12 valve Cummins. Will not fit vehicles equipped with EGR.
Strength: Thick wall flange, 0.25 inch versus the factory 0.15 inch, with a reinforcing rib between flanges. No core charge applies to this part.
Key Features & Benefits
- Ports: CNC machined ports match the factory openings, with a merged runner design that cuts backpressure.
