PPE High-Flow Intake Bridge Manifold Kit - Black Finish (2004.5-2005 GM 6.6L Duramax LLY) - (115053420
Overview
Upgrade the restrictive factory bridge manifold on your LLY Duramax with PPE's High-Flow Intake Bridge Manifold Kit. Designed to increase airflow and improve boost control, this precision-cast assembly delivers stronger performance and better heat management compared to the undersized OEM unit.
Stronger, High-Flow Design
The PPE bridge manifold is cast from A356.0-T6 heat-treated aluminum alloy for exceptional strength and durability. Its enlarged outlets - 32% larger than stock - allow significantly more airflow into the engine, supporting improved throttle response and overall efficiency.
Secure, Leak-Free Construction
A common issue with the factory bridge manifold is the lack of a solid connection between the tube and the manifold, which often leads to boost leaks. PPE solves this by bolting the intake tube directly to the bridge manifold and sealing it with an O-ring for a reliable, leak-free fit.
Complete Bolt-On Kit
This kit includes all required hardware along with upper and lower manifold gaskets for a clean, straightforward installation. The black finish adds a sleek, durable look under the hood while delivering the airflow gains your LLY deserves.
