Diesel Power Source Complete Manifold Kit: Cast Iron Exhaust Manifold + Multi-Layer Gaskets – 2007-2018 Dodge Ram 6.7L Cummins – Direct Fit High Flow Performance Bundle for Lower EGTs

Description

Complete Manifold Kit for 2007-2018 Dodge Ram 6.7L Cummins Upgrade your 2007-2018 Dodge Ram 6.7L Cummins with this comprehensive manifold performance kit from Diesel Power Source. This complete package combines high-flow cast iron manifold construction with premium multi-layer gasket technology, delivering maximum performance, reliability, and convenience in one professional-grade bundle. Complete Kit Includes: High-Flow Cast Iron Exhaust Manifold (OEM replacement for 5135789AB, 5135789AC, 5135789AD) Multi-Layer Manifold Gasket Kit with 4G Gasket All necessary components for complete manifold installation Professional-grade sealing system designed for 6.7L applications Performance Benefits: The high-flow cast iron manifold design significantly reduces exhaust gas temperatures (EGTs) while enabling faster turbo spool-up for improved throttle response and power delivery. Lower EGTs mean reduced stress on engine components, improved fuel efficiency, and enhanced engine longevity under demanding conditions. The optimized flow path maximizes exhaust velocity for superior turbocharger performance on the advanced 6.7L platform. Superior Cast Iron Construction: Built with high-grade cast iron specifically engineered for the demanding environment of the 6.7L Cummins diesel engine. The robust construction withstands extreme heat cycles and high exhaust pressures while maintaining dimensional stability. Cast iron’s superior heat retention properties help maintain consistent exhaust temperatures for optimal turbocharger efficiency. Advanced Multi-Layer Gasket Technology: The included multi-layer manifold gasket kit with 4G gasket provides superior sealing under the high boost conditions typical of 6.7L Cummins applications. The advanced multi-layer construction ensures reliable sealing even under extreme temperature cycling and high exhaust pressures, preventing costly exhaust leaks and maintaining optimal engine performance. Direct Fit Installation: Designed as a direct replacement for factory components with enhanced performance characteristics. The manifold bolts directly to OEM mounting points with no modifications required, while the gasket kit ensures perfect fitment with existing manifold configurations. Compatible with both stock and modified turbo setups on 2007-2018 6.7L applications. Professional Installation Ready: This complete kit eliminates the hassle of sourcing components from multiple suppliers while ensuring perfect compatibility between all parts. The cast iron construction provides the durability needed for professional installations, while the premium gasket system ensures long-term reliability under the demanding conditions of modern diesel performance. Quality Materials & Engineering: Built with materials specifically chosen for 6.7L Cummins applications, including high-temperature resistant gasket materials and precision-cast iron construction. Every component is engineered to withstand the unique challenges of the 6.7L platform, including higher boost pressures, advanced emissions systems, and increased performance demands. Complete System Integration: Every component in this kit is engineered to work together seamlessly with 6.7L Cummins systems. The manifold’s improved flow characteristics are perfectly matched with the advanced sealing system, ensuring consistent performance gains and reliability improvements across the entire exhaust system installation while maintaining compatibility with factory emissions equipment. OEM Quality with Performance Enhancement: This complete manifold kit serves as the foundation for any 6.7L Cummins performance build, whether you’re running a daily driver seeking better efficiency or building a high-performance engine. The combination of improved flow, reliable sealing, and robust construction delivers the performance enhancement and durability your modern Cummins deserves. Modern Diesel Performance: Specifically engineered for the advanced 6.7L Cummins platform, this kit addresses the unique requirements of modern diesel engines including compatibility with emissions systems, higher operating pressures, and increased performance demands. Experience the difference that purpose-built performance parts make in power delivery, component longevity, and overall engine performance. Transform your 6.7L Cummins today with this complete manifold kit and unlock the full potential of your modern diesel engine.
