GMC Sierra Performance Air Intake - Wehrli - WCFab 4in - Bronze Chrome - 01-04. High-flow fabricated aluminum intake and air box for 2001–2004 GMC Sierra HD 6.6L Duramax LB7, finished in Bronze Chrome by Wehrli Custom Fab (WCFab).

This 4-inch kit replaces restrictive factory plastic with smooth-bend aluminum piping and an air box that pulls cool air from the inner fender. The dry filter, hydrophobic pre-filter, and removable lid simplify service while helping protect the MAF, turbo, and engine. Quality silicone couplers, stainless T-bolt clamps, and included hardware make it a straightforward bolt-on with no tuning required. Increased airflow may improve throttle response and turbo sound.
