Why Choose the Vigor Diesel LML Delete Kit?

As part of our comprehensive EGR Delete Kit, this LML version focuses on maximizing long-term engine reliability for heavy-duty trucks:

Prevent Carbon Fouling: Eliminates the recirculation of abrasive soot into the intake manifold, preventing power-robbing carbon buildup and protecting your engine’s internal components.
Optimized Cooling & Airflow: By removing the bulky EGR cooler, this kit significantly improves airflow to the Y-bridge and helps lower Exhaust Gas Temperatures (EGTs), which is critical during heavy towing.
Premium Stealth Construction: Built from 6061 Billet Aluminum and high-grade stainless steel with a black anodized finish for a factory-plus look that resists corrosion and thermal stress.
Reliability for High-Mileage Trucks: Specifically designed for the performance diesel market, this kit addresses the common LML coolant leak and sensor failure points found in the 2011-2016 models.
