GMC Duramax Performance Air Intake - Wehrli - 4in Intake with Air Box - Cat Yellow - 06–07. Fabricated aluminum kit replacing restrictive factory parts to feed your LBZ clean, cool air.

Built for the 2006–2007 6.6L Duramax LBZ, this WCFab/Wehrli system uses 4-inch, smooth-bend aluminum piping to increase airflow and sharpen response while pulling cold air from the inner fender. The enclosed box adds a removable lid for quick checks, and the dry filter includes a hydrophobic Outerwears pre-filter to help keep the MAF and turbo clean. Quality silicone couplers, stainless T-bolt clamps, and all hardware ensure a secure fit. Installs with basic tools; no tuning needed. Cat Yellow powder coat. Made in USA.
