K&N 20-26 GM Heavy Duty 6.6L Diesel NextGen Dry Flow Cold Air Intake
K&N 20-26 GM Heavy Duty 6.6L Diesel NextGen Dry Flow Cold Air Intake
K&N Engineering
This K&N NextGen Diesel Dryflow cold air intake system is engineered for GMC/Chevrolet Sierra/Silverado 2500/3500 V8 6.6L DSL. A high-density polyethylene (HDPE) rotationally molded tube helps increase the volume of airflow by 41.4% CFM GAIN to your engine and provides an increase of 23.7 horsepower and 24.7 torque with no tune required. This intake system is paired with a washable, reusable Dryflow LIFETIME Air Filter featuring an oil-free synthetic media. The oversized, conical design allows you to go up to 50,000 miles between filter services under normal highway driving conditions and has an easy oil-free two step cleaning process for convenience. A custom designed NextGen air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 60 minutes.This Part Fits:
