K&N NextGen Dryflow Cold Air Intake for 2020-2026 Chevrolet Silverado/GMC Sierra 2500/3500 HD (6.6L) 50-3119D

Fits select 2020-2026 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD models (6.6L).

The K&N NextGen Diesel Dryflow cold air intake system (MPN 50-3119D) is engineered to maximize airflow and thermal efficiency for heavy-duty GM 6.6L diesel engines. This system replaces the restrictive factory air path with a high-density polyethylene (HDPE) rotationally molded tube, designed to increase airflow volume to the turbocharger for improved throttle response and performance without requiring an ECU re-tune.

This intake features an oversized, conical Dryflow air filter utilizing oil-free synthetic media. This design provides up to 99% filtration efficiency and simplifies maintenance with a two-step cleaning process that eliminates the need for filter oil. The included custom-molded NextGen air box isolates the intake tract from high under-hood temperatures, ensuring a cooler, denser air charge enters the engine. The system is designed for a straightforward installation that typically takes under 60 minutes using standard tools.

• Increased Airflow: Rotationally molded HDPE tube optimizes air velocity and volume.
• Dryflow Technology: Washable, reusable oil-free synthetic media simplifies service.
• Extended Service Interval: Go up to 50,000 miles between cleanings under normal highway conditions.
• Thermal Protection: NextGen air box shields the intake from engine bay heat.
• No Tune Required: Engineered to operate safely with factory engine management.
• MPN: 50-3119D
