Wehrli 01-04 Duramax LB7 4in Intake Kit with Air Box Stage 2 - WCFab Red

The Wehrli Stage 2 Bengal Red Air Intake System is engineered to replace restrictive factory components in 2001-2004 Chevrolet Silverado and GMC Sierra 6.6L Duramax (LB7 engine) models. This high-flow, fabricated aluminum intake kit significantly boosts airflow to your turbocharger, translating into increased horsepower, enhanced torque, and quicker throttle response.

Crafted from durable aluminum, the system features 4-inch diameter piping with aerodynamic bends that optimize air velocity and volume. This design not only improves performance but also delivers an aggressive engine sound during acceleration. The included air box, with its removable lid, facilitates easy maintenance and visual inspections, while a hydrophobic pre-filter cover helps protect the MAF sensor and engine airways from contaminants. It is compatible with both OEM and upgraded IHI style turbochargers.

Installation of this bolt-on kit is straightforward, requiring only basic tools and no additional tuning. It draws cooler air through the inner fender, further enhancing performance. Made in the USA, this custom Bengal Red powder-coated system ensures a perfect fit and lasting durability. (California Residents: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov)
