BD Diesel Exhaust Manifold Kit – Part # 1046047

The BD Diesel 98.5-02 Dodge 5.9L 24-Valve Cummins Pulse Exhaust Manifold Kit offers a high-quality replacement designed for durability and performance. Constructed from high-silicon ductile iron, this exhaust manifold is engineered to withstand extreme temperatures and vibration, ensuring long-term reliability in demanding applications. Its fully divided pulse design optimizes exhaust flow, which can enhance engine efficiency and power output while reducing backpressure. The manifold features modern internal geometry, with precision slip joints that allow for expansion and contraction, effectively minimizing the risk of cracking and exhaust leaks caused by cyclic thermal fatigue. This design innovation significantly prolongs the lifespan of the manifold, making it an ideal choice for stock or performance-oriented installations.
The kit includes all necessary components for a straightforward installation, such as gaskets, bolts, and spacers. The grade 10.9, black oxide-coated bolts and spacers provide corrosion resistance and added strength, suitable for heavy-duty use. Pre-drilled ports for pyrometer probes facilitate temperature monitoring for tuning and diagnostics. Additionally, this exhaust manifold is pre-drilled for turbo mount compatibility, making it a versatile upgrade compatible with various configurations. Certified under SEMA and compliant with EPA standards, this manifold replaces Cummins part number 3946036, ensuring a precise fit for Dodge Ram 2500 and 3500 trucks from 1998 through 2002.
Designed for both stock and performance applications, the BD Diesel pulse exhaust manifold is a reliable upgrade that enhances exhaust flow, engine durability, and thermal management. Its robust construction and included hardware make it a valuable addition to any heavy-duty diesel engine maintenance or upgrade project, providing confidence in demanding fleet and off-road environments.
