Product Fitment

The Duramax DPF Delete Plug kit is designed for 2011-2023 GM/Chevy 6.6L LML/LGH & L5P/L5D Duramax trucks. This kit offers a durable and weatherproof solution, especially for protecting unused exhaust and EGR harness connectors. Therefore, trucks with emissions modifications benefit greatly, as this kit keeps the wiring secure and safe from moisture or dirt.

Key Features

  • Simple Installation: You can install the caps quickly, without needing special tools. Additionally, the caps snap easily into place, providing a fast and secure setup.

Benefits of Duramax DPF Delete Plug kit

  • Prevents Wiring Damage: The weatherproof seals actively guard your wiring from corrosion and environmental elements. Thus, this kit helps prolong the life of important engine components.
  • Professional Appearance: After emissions components are removed, the caps maintain a factory-like appearance, keeping your engine bay tidy and protected.
  • Optimized for Performance: Trucks with EGR and exhaust system modifications benefit from this kit. Therefore, it's ideal for off-road or performance-focused builds.

Installation & Compatibility

  • Vehicle Fit: This kit fits 2011-2023 GM/Chevy 6.6L Duramax trucks (LML/LGH & L5P/L5D models).
  • Installation Time: It typically takes less than 30 minutes to install using basic hand tools.

Additional Information
