Wehrli 06-07 Chevrolet Duramax 6.6L LBZ Stage 2 High Flow Intake Bundle Kit - WCFab Red

The Wehrli Stage 2 High Flow Intake Bundle Kit for the 2006-2007 Chevrolet Duramax 6.6L LBZ is a performance upgrade designed to significantly enhance airflow to the turbocharger. Constructed from all aluminum 14 gauge material, it features large diameter 4-inch piping with smooth aerodynamic bends to improve intake air velocity and volume. The kit includes a 4.8-inch turbo intake horn, the largest available, providing a 20% airflow increase over stock. Additional features include high-quality hardware, silicone boots, seals, and stainless steel t-bolt clamps for durability and ease of installation. The removable air box lid element with a hydrophobic pre-filter cover allows for easy inspection and maintenance, helping keep the MAF sensor, turbo, and engine airways free of contaminants. Upgraded intercooler pipes, including a heavy-duty 3-inch driver side and 3.5-inch passenger side, replace restrictive stock components, with CNC machined flanges and double o-ring seals for higher boost pressures and reliability.

Designed specifically for 2006-2007 Chevrolet Duramax LBZ engines, this bolt-on intake bundle is ideal for improving performance in street and towing applications. It replaces factory components with heavy-duty, high-flow parts made in the USA, including mandrel-bent aluminum pipes and reinforced silicone boots with stainless steel clamps. The kit also features a high-flow 3-inch Y-Bridge to optimize airflow after the turbo. Suitable for daily driving, towing, and performance enthusiasts, this Stage 2 kit enhances horsepower, torque, and turbo sound while maintaining durability and reliability under higher boost conditions. Installation is straightforward, with all necessary hardware included for a comprehensive upgrade.
