BD DIESEL EXHAUST MANIFOLD 20 DEGREE (T4) 98.5-18 CUMMINS - 1045996-T4

Enhance the performance of your CUMMINS 5.9L/6.7L 24V engine with the BD Diesel 1045996-T4 Exhaust Manifold, specifically designed for 1998.5-2018 models. This exhaust manifold is engineered to safeguard your turbocharger by incorporating a waste gate mechanism into its design. The cast and machined wastegate port effectively divides the manifold into two sections, preserving the divided pulse manifold flow.

Utilizing Computational Fluid Dynamics (CFD), the internal geometry of this manifold is optimized to enhance flow efficiency across the entire RPM range, ideal for high flowing T4 or T6 based turbochargers. Crafted from thick-wall cast high silicone ductile iron, this manifold effectively retains heat energy for optimal performance. The precision slip joints built into the design allow for expansion and contraction, reducing cyclic thermal fatigue and significantly extending the longevity of the manifold.

Featuring pre-drilled and tapped 1/8-NPT ports, the BD Diesel Exhaust Manifold offers ease of installation and compatibility with additional accessories. Designed to improve turbo response, this manifold provides better cylinder exhaust evacuation to help maintain exhaust gas temperatures at an optimal level.

For added convenience, this product is backed by a 36-month or 75,000-mile warranty on parts, ensuring your satisfaction and peace of mind. Please note that this product is not available for sale in California.

Experience the BD Diesel difference with this high-quality Exhaust Manifold, meticulously crafted to meet your performance needs and turbocharger protection requirements. Unlock the full potential of your engine with the BD Diesel 1045996-T4 Exhaust Manifold.

Protect your turbocharger with a performance manifold designed with a waste gate in mind. Cast and machined wastegate port completely divides the manifold into two sections to retain the divided pulse manifold flow. Internal geometry is optimized through Computational Fluid Dynamics (CFD), which increases flow throughout the RPM band for your high flowing T4 of T6 based turbo. Thick-wall cast high silicone ductile iron retains heat energy. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increase manifold longevity. 1/8-NPT ports are pre-drilled and tapped.
