Product Description

DHD 201-102 LLY Duramax 3" High Flow Intake Y-Bridge 2004-2005 6.6L

Replace your factory restriction intake manifold pieces with our DHD LLY High Flow Intake Kit. This kit is a complete one-piece intake manifold upgrade. Our intake is assembled from mandrel bent aluminum tubing which allows for a massive increase in intake volume. When compared to the factory intake plumbing our high flow intake bridge flows an impressive 152% more volume. See the chart below for details. This intake will not only increase horsepower, torque and airflow throughout the engine, but it will also reduce EGTs and drive pressure. The reduction in EGT and drive pressure will help yield a longer running, healthier engine.

This kit includes the main intake assembly and all necessary hardware for installation. We recommend our DHD 700-125 or 700-155 Fuel Block Upgrade kit when installing our LLY High Flow Intake.

If you have a large alternator, you may have to trim the battery lug on the back of the alternator or rotate the rear half of alternator.


Note: Some modifications to the fuel return line will be needed.
