Chevrolet Silverado 2500 Performance Air Intake - Wehrli - 4in Intake Kit - Sparkle Copper - 2006–2007. A high-flow fabricated aluminum intake and air box that replaces the restrictive factory setup on your LBZ Duramax.

This WCFab system significantly increases airflow to the turbo for improved horsepower and torque, quicker throttle response, and cooler intake temps by drawing cold air through the inner fender. The all-aluminum 4in piping uses smooth bends to enhance air velocity and volume, delivering a more assertive engine and turbo sound under throttle. A dry filter sits inside a sturdy air box with a removable lid for easy inspection, while the included hydrophobic Outerwears pre-filter helps keep contaminants at bay. Quality silicone boot, seals, and stainless T-bolt clamps ensure durability. Bolt-on install with basic tools; no tuning required. Made in the USA and finished in Sparkle Copper.
