Why does my 2006/2007 LBZ need a High-Flow Intake Elbow?

The factory LBZ intake bridge is highly restrictive and acts as a bottleneck for air volume. By using this lbz egr delete kit with the high-flow elbow, you increase airflow by nearly 35%, allowing your turbo to spool faster and lowering EGTs significantly.

Is tuning required for this lbz duramax egr delete kit?

Yes. Once the EGR hardware is removed, the ECU will detect the missing components and trigger a "Limp Mode." You must use a tuner (e.g., EFI Live or SCT) to recalibrate the engine.

Will this kit help with the common LBZ overheating issues?

Yes. The EGR system contributes heavily to heat soak in the engine bay. Removing it reduces engine bay temperatures by about 7°C and EGR zone heat by 20°C, giving your cooling system more breathing room.

How long is the installation for this kit?

For most DIYers with standard tools, installation takes approximately 2-3 hours. All components are direct bolt-on replacements.

What makes Vigor Diesel's kit better than basic block-off plates?

Basic plates only stop the soot; our kit fixes the intake restriction. By replacing the intake bridge, you get a performance gain that simple block-off plates can't offer.
