Product details
WC Fab 4" Intake Kit with Air Box - Semi-Gloss Black - LB7 Duramax
WC Fab's Stage 1 4-inch intake system replaces the restrictive factory intake components on 2001-2004 LB7 Duramax trucks with a fabricated-aluminum intake pipe, enclosed air box and dry-filter assembly. The larger, smoother airflow path is designed to feed the turbo with less restriction for improved throttle response, airflow and turbo sound.
This listing is finished in Semi-Gloss Black. The system is designed as a bolt-on upgrade for the supported truck configuration and retains the application-specific connections needed for proper installation.
