• Optimized Gas Flow: Designed to streamline exhaust expulsion, which enhances turbocharger response and fuel efficiency.
• Perfect Fitment: Specifically engineered for Cummins 4B3.9, B4.5, and QSB3.9 engines, ensuring a leak-free seal and easy installation.
• Thermal Management: Facilitates rapid heat dissipation to protect surrounding engine components and maintain optimal operating temperatures.

Technical Specifications

• Weight: 15.87 lb
• Dimensions: 18.8 x 8.6 x 6.13 in
• Compatibility: Cummins 4B3.9, B4.5, QSB3.9, 30 CM550

Regular inspection of the exhaust manifold is vital. Replacing a worn or cracked manifold with the 3901635 model helps prevent exhaust leaks that can lead to power loss and increased emissions.
