The Wehrli WCF100684-GB Intake Kit Stage-2 is a high-performance intake system designed for the 2020-2025 Duramax L5P 6.6L engines. Constructed with fabricated aluminum, it features a large diameter 4-inch piping with smooth aerodynamic bends to enhance intake air velocity and volume. The kit includes an air box enclosure and a dry filter assembly that replaces the restrictive plastic factory components, resulting in improved airflow to the turbo. This upgrade increases horsepower and torque, delivers quicker throttle response, and reduces intake temperatures by drawing cold air through the hood Ram Air duct and inner fender. The all-aluminum construction not only boosts performance but also provides durability and a more aggressive turbo sound during acceleration. The intake horn is over an inch larger than OEM, further improving airflow by removing restrictions before the turbo inlet. The assembly can be finished in custom powder coat colors for a personalized look.
Designed for 2020-2025 Chevrolet Silverado and GMC Sierra HD trucks equipped with the L5P 6.6L Duramax engine, this intake kit is a direct bolt-on upgrade. It replaces GM Part Numbers 84841229, 84841225, 84262962, 85614333, and 84554702, making it compatible with factory mounting points and connections. Ideal for street performance, towing, and daily driving, it enhances engine breathing and overall power output. The kit includes all necessary components for installation, providing a straightforward upgrade for those seeking improved engine efficiency and sound. This intake system is suitable for enthusiasts looking to maximize their truck’s performance while maintaining a clean, custom appearance.
