Description

The WEHRLI CUSTOM FAB WCF100190 is a premium airflow upgrade for early LB7 trucks, designed to replace the restrictive factory plastic intake system. This kit features a high-flow 4-inch fabricated aluminum intake pipe and a durable enclosed air box. It aims to help your 6.6L Duramax breathe easier under load, improve turbo response, and deliver a cleaner, more aggressive engine tone when you get into the throttle. It offers high-quality aluminum construction, enclosed filtration, a smooth airflow path, a dry filter assembly, and true bolt-on installation without requiring tuning.
