For 2011-2017 GM 6.6 6.6L LML Duramax Diesel PCV Reroute Kit W/ Resonator Plug

What is For 2011-2017 GM 6.6 6.6L LML Duramax Diesel PCV Reroute Kit W/ Resonator Plug?

This PCV reroute kit is engineered specifically for 2011–2017 GM 6.6L LML Duramax diesel engines. It completely removes the factory EGR valve and EGR cooler from the system, redirecting crankcase vapors away from the intake. Designed for off-road use, the kit helps reduce engine heat and prevents carbon accumulation in the intake manifold—a common issue on stock LML engines. By eliminating hot exhaust gas recirculation, it promotes cleaner airflow, cooler intake temperatures, and enhanced engine longevity. The included resonator plug seals the factory resonator port for a complete installation.

Key features

• Full EGR Elimination — Replaces EGR valve and cooler; no additional parts needed.
• Cooler Engine Operation — Prevents hot exhaust gases from re-entering the intake tract.
• Improved Reliability — Reduces carbon buildup in intake manifolds and turbo systems.
• Direct Fit Design — Custom-molded hoses and fittings for LML Duramax applications.
• Includes Resonator Plug — Seals off resonator port for complete PCV reroute.
• Off-Road Use Only — Not compliant with emissions regulations for street use.
• High-Quality Materials — Heat-resistant hoses and durable connectors for long-term performance.

Who is For 2011-2017 GM 6.6 6.6L LML Duramax Diesel PCV Reroute Kit W/ Resonator Plug for?

This kit is ideal for Duramax diesel owners who use their trucks off-road, in towing applications, or in high-mileage service where engine reliability is critical. It’s especially beneficial for those experiencing EGR cooler failures or intake coking. Enthusiasts upgrading their engine’s breathing system will appreciate the simplified setup and reduced maintenance. Not recommended for daily drivers in regulated emissions states.

How does For 2011-2017 GM 6.6 6.6L LML Duramax Diesel PCV Reroute Kit W/ Resonator Plug compare?

Compared to stock EGR systems, this reroute kit eliminates a major source of engine heat and carbon deposits. Unlike partial EGR blockers or delete plates, it fully replaces the system for a cleaner installation. It outperforms basic PCV filters by integrating a sealed reroute path and resonator plug. While similar to other LML delete kits, this version includes all necessary components for a complete install without sourcing extra parts. It’s a cost-effective alternative to full EGR cooler replacement, especially in high-stress environments.
