115053420 | PPE Performance GM 6.6L Duramax LLY High-Flow Intake Bridge Manifold Kit | Black Finish

Upgrade the notoriously undersized stock bridge manifold in your LLY to the bigger and better PPE bridge manifold. Cast from A356.0-T6 heat-treated aluminum alloy, this bridge manifold delivers durability, increased airflow, and improved heat management.

Boost leak is another common issue on the stock bridge manifold/tube, because of the lack of physical connection between the two components. The PPE intake manifold tube is securely bolted to the bridge manifold and sealed with an O-ring to prevent boost leaks.

Kit includes all necessary hardware, upper and lower manifold gaskets. 

Note: PPE Lower Intake Manifold Kit SKU 115051500 is required for the installation of this kit because of the larger bridge manifold outlets.
