K&N 2020-2026 GM Heavy Duty 6.6L Diesel NextGen Dry Flow Cold Air Intake

K&N NextGen Cold Air Intake for 2020-2026 GM 6.6L Duramax Diesel | 50-3119D

Boost your 2020-2026 Chevy/GMC 6.6L Duramax Diesel performance with the K&N NextGen Cold Air Intake. Features a Dryflow filter, HDPE intake tube, and dyno-proven power gains.

The K&N NextGen Series 50 Intake is a specialized performance upgrade designed for the 2020-2026 GM 6.6L Duramax Diesel engine. It replaces the restrictive factory air box and intake path with a custom-engineered high-density polyethylene (HDPE) rotationally-molded tube. This system significantly streamlines airflow, resulting in estimated gains of 23.7 HP and 24.7 lb-ft of torque. The hybrid semi-enclosed airbox helps isolate the intake air from engine heat, ensuring a cooler, denser oxygen charge for improved combustion efficiency.

Best Uses

1. Heavy-Duty Towing: Provides the extra torque needed when hauling trailers or heavy payloads.
2. Highway Passing: Improves throttle response for more confident overtaking on open roads.
3. Off-Road Exploration: The enclosed airbox design helps protect the filter from engine heat and dust.
4. Low-Maintenance Performance: Ideal for owners who want performance gains without the hassle of re-oiling filters.

Features

1. NextGen DryFlow Media: A synthetic, non-oiled filter that simplifies cleaning while maintaining high filtration efficiency.
2. Rotomolded HDPE Intake Tube: Designed to smooth and straighten airflow, reducing turbulence into the turbocharger.
3. Enclosed Air Box Design: Shields the intake air from high engine bay temperatures to ensure a cooler air charge.
4. Direct Bolt-On Installation: Specifically designed to fit factory mounting points; typically installs in under 60 minutes with basic hand tools.
5. Oversized Conical Filter: Provides a larger surface area than stock filters, allowing for service intervals up to 50,000 miles depending on conditions.
