Is it time to upgrade the capabilities of your 6.6L Duramax L5P? When you get more, colder, and denser air into the engine, it enables the engine to burn fuel more efficiently, and a better burn = more power. You can expect to see horsepower gains of 21 Horsepower and 35 more FT/LBS of torque. This is a foundational mod that enhances any truck, whether it's a daily driver or a dedicated race truck.
The K&N NextGen Diesel Dryflow cold air intake systems feature a high-density polyethylene (HDPE) rotationally molded tube, designed to help increase airflow volume to your engine. This intake system is paired with a washable, reusable Dryflow LIFETIME Air Filter featuring an oil-free synthetic media. The oversized, conical design allows for up to 50,000 miles between filter services under normal highway driving conditions and features an easy, oil-free two-step cleaning process for added convenience. A custom-designed NextGen air box helps protect the air intake from the high temperatures of your engine bay, and the entire system can typically be installed in under 60 minutes.
