D&J Precision Machine Billet Stage 2 Intake Manifold

Billet Stage 2 Intake Manifold

The Billet Stage 2 Intake Manifold is specifically designed for our Stage 2 cylinder heads. It is available with either 5.9 intake and fuel setups or 6.7 intake and fuel setups. These intakes utilize the stock intake horn locations and fuel setups and come with all the mounting hardware needed for installation.

Key Features:

• Compatibility: Designed for Stage 2 cylinder heads with options for 5.9 or 6.7 intake and fuel setups.
• Stock Locations: Utilizes the stock intake horn locations and fuel setups for ease of installation.
• Enhanced Performance: Allows you to port and polish the intake side of the head for improved airflow.
• Complete Kit: Includes all necessary stainless steel mounting hardware for a complete installation.

Performance Insight:

• Optimal Air Distribution: We do not offer a side entrance intake due to observed poor air distribution with such designs. Side entrance intakes can cause uneven air distribution, leading to cylinders across from the inlet being overloaded with air. This can result in exhaust gas temperature differences of up to 400 degrees, potentially causing piston issues and imbalanced airflow levels across cylinders.

Upgrade to our Billet Stage 2 Intake Manifold for a reliable and performance-oriented solution for your 5.9 or 6.7 Cummins engine.
