Chevrolet Duramax Performance Air Intake - Wehrli 4 in. Intake Kit with Air Box, Chevy Orange, for 2004.5-2005 GM 6.6L Duramax LLY. A high-flow fabricated aluminum intake and enclosed air box that replaces restrictive factory parts to let your LLY breathe easier.

Built around large 4 in. aluminum piping with smooth bends, this kit increases airflow to the turbo for crisper throttle response and helps lower inlet temps by drawing fresh air from the inner fender. The sealed box uses a serviceable dry filter and a hydrophobic pre-filter cover to help keep the MAF, turbo, and intake tract clean. A removable lid simplifies inspection, while the included silicone boot, seals, and stainless T-bolt clamps ensure a secure, durable install. Finished in Chevy Orange powder coat. Bolt-on fitment; no tuning required. Made in the USA.
