Product Description

The K&N 50-3119D is a NextGen Diesel Dryflow Cold Air Intake System engineered specifically for 2020-2026 GM Heavy Duty trucks powered by the 6.6L Duramax L5P turbocharged diesel engine, covering all Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trim levels. Replacing the restrictive factory airbox and intake tubing with a large-diameter HDPE rotationally molded tube and a semi-enclosed NextGen hybrid airbox, this system delivers up to 21 HP and 35 lb-ft of torque gains with no tune required. Cold, dense air is drawn through an oversized conical Dryflow filter and efficiently channeled through strategically positioned air channels in the intake tube, maximizing airflow volume to the engine for improved towing, hauling, and overall L5P Duramax performance.

The oil-free Dryflow synthetic filter requires no re-oiling and is serviceable up to every 50,000 miles - a clear maintenance advantage over traditional oiled cotton intakes. The all-black NextGen airbox and tube deliver a clean, aggressive appearance in any 2020-2026 HD engine bay. The entire system installs in under 60 minutes with no cutting required and is backed by K&N's Million-Mile Limited Warranty.
