PPE High-Flow Intake Bridge Manifold Kit GM 6.6L Duramax LLY

PPE High-Flow Bridge Manifold Kit

Upgrade the restrictive factory intake bridge on your LLY Duramax with the PPE High-Flow Bridge Manifold Kit. Cast from high-strength A356.0-T6 heat-treated aluminum alloy, this manifold features significantly larger outlets for improved airflow, enhanced durability, and better overall engine performance. The innovative bolted intake manifold tube design eliminates a common source of boost leaks found in the factory setup.

Key Features

• Constructed from durable A356.0-T6 heat-treated aluminum alloy
• Precision cast using permanent steel molds for consistent quality
• 32% larger outlet ports increase airflow capacity
• Bolted intake manifold tube design helps eliminate boost leaks
• Integrated O-ring seal provides a secure connection between components
• Improves airflow and intake system efficiency
• Direct bolt-on installation
• Includes all required hardware and gaskets

Benefits

The larger flow capacity of the PPE bridge manifold reduces intake restriction and supports improved engine performance. By securely fastening the intake tube to the manifold and sealing it with an O-ring, this kit helps prevent boost leaks that are common with the factory design, improving reliability and maintaining consistent boost pressure.

Fitment

Designed for LLY Duramax diesel applications. PPE Lower Intake Manifold Kit (SKU 115051500) is required for installation due to the larger bridge manifold outlet size.
