Chevrolet Silverado Performance Air Intake – Wehrli Intake Horn, Sparkle Bomber Orange (2011–2016). A cast-aluminum turbo inlet horn that replaces the restrictive OEM piece to improve airflow and response.

Built by Wehrli Custom Fabrication for Duramax LML trucks, this 4.8 in inlet horn deletes the factory resonator, adds a dedicated PCV port, and pairs with WCFab Stage 1 LML Intake and High Flow kits. Finished in Sparkle Bomber Orange custom powder coat. Intake must use a silicone boot at the horn (accepts a 4 in boot and clamp); not compatible with molded, built-in rubber connections or aftermarket LML Y-bridges that relocate the inlet. 2011 trucks must update the PCV regulating valve to 2012–2016 spec. Replaces GM 12642296 and 12637801.
