For owners of 12-valve and 24-valve 5.9L Cummins engines who want to upgrade to the larger, higher-flowing 6.7L Cummins intake horn, the G&R Diesel Intake Conversion Plate delivers a reliable, precision-engineered solution. This billet component allows you to modernize your intake manifold setup, unlocking improved airflow potential for enhanced performance in modified, high-horsepower, or efficiency-focused builds.

Premium Construction & Materials

CNC-machined from high-quality billet aluminum, this conversion plate is built for strength, durability, and a perfect fit. It replaces the factory intake plate, providing a robust mounting surface specifically designed to accept 6.7L Cummins intake horns while maintaining structural integrity under boost and vibration.

Important Installation Considerations

• This plate is designed specifically to adapt and secure a 6.7L intake horn. It is not a complete intake manifold conversion.
• Fuel Line Clearance: Depending on your specific intake horn choice, turbo configuration, and other modifications, fuel lines may require rerouting or additional adjustments to avoid interference.
• Fitment Note: Due to the wide variety of aftermarket intake horns, turbochargers, and related components available in the Cummins performance market, we recommend verifying compatibility with your specific setup. G&R Diesel cannot guarantee fitment across every possible combination.

Why Choose the G&R Diesel Intake Conversion Plate?

This conversion plate is a smart, cost-effective way to bridge the gap between generations of Cummins engines, giving your 5.9L the benefits of a larger intake horn without a full manifold swap. It reflects G&R Diesel’s commitment to practical, high-quality parts that help enthusiasts achieve their performance goals while maintaining reliability.
