Wehrli Custom Fabrication WCF100414-GM Stage High Flow Intake Bundle Kit Duramax - 2 for L5P

The Wehrli Custom Fabrication Stage 2 High Flow Intake Bundle Kit combines the Stage 1 High Flow Bundle and Stage 2 Intake Kit into a single package designed for 2020-2026 L5P 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500/3500 trucks, providing increased airflow for improved efficiency, throttle response, and turbo spool up.

Air Intake System Features:

• High-flow fabricated 4-inch intake pipe, intake horn, and air box enclosure with dry filter assembly replaces restrictive plastic factory parts for improved engine performance and sound
• Intake horn is over an inch larger than OEM diameter
• Air box constructed of 10-gauge aluminum sheet with removable lid for easy maintenance
• Significantly increases airflow to turbo producing improved horsepower and torque and cooler intake temperatures by drawing cold air through the hood ram air duct and inner fender
• Includes hydrophobic pre-filter cover to help keep MAF sensor, turbo, and engine airways contaminant-free

Intercooler Pipe Upgrades:

• Upgrades the restricted 2-piece 2.5-inch diameter driver (hot) side intercooler pipe and leak-prone 2-piece plastic/rubber passenger (cold) side pipe with heavy duty 3-inch diameter 1-piece driver side and 3.5-inch diameter passenger side L5P intercooler pipes
• Made in the USA from high strength, heavy duty 14-gauge aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow
• Driver side pipe eliminates the OEM middle boot joint and includes high quality reinforced silicone boots and stainless t-bolt clamps for superior temperature resistance and boost pressure holding capabilities
• Passenger side pipe features a CNC machined flange with double o-ring seal and upgraded silicone boot to withstand higher boost pressures and eliminate boost leaks

This comprehensive kit eliminates weak points in the factory design that can contribute to lost power, boost leaks, and complete failures in hard-working and high-performance applications. Easy installation using basic hand tools with no tuning required. Available in multiple powder coat color finishes including WCFab Red, WCFab Grey, Gloss Black, Gloss White, Illusion Purple, and Candy Teal.
