This is a 4-inch fabricated aluminum cold air intake kit for the 2017-2019 Chevrolet Silverado and GMC Sierra with the 6.6L Duramax L5P diesel. It replaces the factory plastic intake tube and air box with an aluminum pipe, an enclosed air box and a dry filter, and it pulls air through the hood Ram Air duct and inner fender. The pitch is more airflow to the turbo, quicker throttle response and cooler intake temperatures than the stock setup. It suits L5P owners who tow or run a tune and want a sturdier, higher-flow intake; the trade-offs are a dry filter that needs cleaning and more intake sound than stock.
