The Wehrli 11-16 Chevrolet Duramax LML 4in Intake Kit is a high-performance intake system designed to enhance the airflow and overall efficiency of the 6.6L Duramax diesel engine. Constructed from fabricated aluminum, this kit includes a 4-inch intake pipe and an air box enclosure with a dry filter assembly, replacing the restrictive factory plastic components. Its design significantly boosts airflow to the turbocharger, resulting in increased horsepower, torque, and quicker throttle response. The large diameter piping with smooth aerodynamic bends improves intake air velocity and volume while producing a more aggressive engine and turbo sound. Durable hardware, silicone boots, seals, and stainless steel t-bolt clamps ensure a secure fit and long-lasting performance. The air box features a removable lid for easy filter inspection and maintenance, with a hydrophobic pre-filter cover to protect the MAF sensor and engine airways from contaminants. The entire assembly is finished in a gloss black powder coat for a sleek, custom appearance.

This intake kit is specifically engineered for 2011 to 2016 Chevrolet trucks equipped with the GM LML 6.6L Duramax engine. It serves as a direct replacement for the factory intake system, offering a bolt-on installation that improves cold air intake by drawing air through the inner fender. The kit is ideal for street, towing, and daily driving applications where enhanced engine performance and reliability are desired. Included components ensure a complete upgrade, making it suitable for enthusiasts seeking improved power delivery and cooler intake temperatures without extensive modifications.
