Closed-Box Isolation and High-Flow MaxFlow 5 Oiled Media

Engineered specifically for 2013–2016 GM 2500HD/3500HD trucks (and late 2012 dual-sensor models) equipped with the 6.6L LML Duramax diesel engine, the Volant 15566 cold air intake replaces the restrictive factory air tract with a high-capacity velocity airbox and a smooth-bore intake duct. By completely isolating the air filter inside an insulated cross-linked polyethylene enclosure, the system prevents power-sapping hot engine bay air from entering the intake charge, delivering dense, cool ambient air directly into the turbocharger.

Key Features & Benefits

• Enclosed Air Box Design: Insulates the air filter from radiant engine heat and road debris, maximizing air charge density and lowering intake temperatures.
• Dual Sensor Accommodation: Specifically molded to fit both the factory Mass Air Flow (MAF) sensor and Air Temperature Sensor (ATS) found on 2013–2016 models.
• MaxFlow 5 Oiled Filtration: Five layers of progressively finer cotton gauze media deliver high airflow rates and long service intervals up to 40,000 miles.
• High-Velocity Intake Duct: Precision-molded cross-linked polyethylene intake tube eliminates internal turbulence and factory resonator restrictions.
• Direct Bolt-On Installation: Mounts directly into factory mounting locations with high-temperature silicone connectors and marine-grade stainless steel clamps.
