Chevrolet Duramax Performance Air Intake – Wehrli 5in Intake Horn, Sparkle Copper, for 2011–2016 GM Duramax LML. A high-flow cast aluminum upgrade to the restrictive factory inlet.

Featuring a 4.8 in inlet and 5 in horn, it boosts airflow to the turbo for quicker response. It includes a PCV port and deletes the resonator for a more pronounced turbo note. Requires an intake pipe that accepts a 4 in silicone boot and clamp; not compatible with molded-coupler intakes. 2011 trucks need the 2012–2016 PCV valve update. Not compatible with aftermarket LML Y-bridges that relocate the inlet.

Features

• Cast aluminum, Sparkle Copper powder coat
• Silicone reducer boot and stainless T-bolt clamps
• O-ring seal and new EGR gaskets
• Replaces GM 12642296 and 12637801
