Elevate your GM 6.6L Duramax performance with the PPE Lower Intake Manifold Kit.

The PPE lower intake manifolds are cast from A356.0-T6 heat-treated aluminum alloy, a strong, durable, corrosion-resistant, and thermally efficient casting material. The kit retains all factory mounting locations including those for LLY and LBZ/LMM fuel rails, EGR brackets, and fuel line brackets. A built-in MAP sensor port ensures seamless integration on LLY applications. A dummy plug is also provided for LBZ/LMM applications where the MAP port on the lower manifold is not used (the MAP sensor is located near the grid heater on those engines).

Kit includes all necessary hardware.

Note: For LLY applications, the PPE Intake Bridge Manifold SKU 115053400 is also required. This combination is port-matched for optimal performance and airflow distribution.

For LBZ/LMM applications, the PPE Intake Bridge Manifold and Tube Kit SKU 115053600 is not required but recommended.
