PPE High Flow Intake Bridge Manifold Kit 04.5-10 GM 6.6L Duramax LLY/LBZ/LMM

Need to improve airflow and eliminate one of the biggest intake restrictions on your Duramax? The PPE High-Flow Intake Bridge Manifold Kit is designed to deliver increased airflow efficiency, lower exhaust gas temperatures, and improved throttle response by replacing the restrictive factory intake components. The stock LLY intake system is well known for airflow limitations that can reduce performance, especially on tuned or higher-horsepower applications. PPE’s upgraded intake bridge and manifold system helps your Duramax breathe more efficiently, supporting improved overall engine performance while enhancing reliability under load. Whether your truck is built for towing, daily driving, or performance use, this kit provides a substantial airflow upgrade over the factory setup. IMPORTANT INFO: PPE Lower intake manifold kit is required for the installation of this kit because of the larger bridge manifold outlets. Built for durability and performance, the PPE High-Flow Intake Bridge Manifold Kit features heavy-duty cast aluminum construction engineered to withstand high boost pressure and demanding operating conditions. The larger internal passages and optimized design help reduce airflow restriction and improve air distribution into the engine, enabling more efficient combustion and consistent cylinder balance. Precision-machined mating surfaces ensure proper sealing and fitment, while the durable finish provides corrosion resistance and a clean underhood appearance.
