Chevrolet Silverado 2500HD Performance Air Intake – Wehrli 4in Intake Kit with Air Box in Chevy Orange for 2001–2004 Duramax LB7. This fabricated aluminum system replaces restrictive stock parts for cleaner, stronger airflow.

Built for the LB7, the large 4 in piping and smooth bends improve air velocity to the turbo, supporting gains in response and helping reduce intake temperatures by drawing cool air from the inner fender. The enclosed air box features a removable lid for quick filter checks, and the dry filter pairs with a hydrophobic pre-filter cover to help keep the MAF and compressor clean. Quality silicone boot, seals, and stainless T-bolt clamps ensure a solid fit. Finished in Chevy Orange powder coat, this bolt-on kit installs with basic hand tools and requires no tuning. Made in the USA.
