Chevrolet Duramax LMM Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Illusion Blueberry - `07-`10. A high-flow, bolt-together upgrade that replaces the restrictive OEM upper intake on 2007.5–2010 Duramax LMM trucks.

This Y-bridge addresses the slip-fit factory design that can separate under boost, delivering a secure seal and consistent drivability. The two-piece 3 in assembly pairs with 3 in upper and lower intercooler pipes featuring smooth-flowing mandrel bends and CNC-machined billet flanges. It retains the factory grid heater, throttle valve, and EGR connections, installs on stock trucks with no tuning required, and comes finished in Illusion Blueberry. Compatible with the OEM passenger-side lower intercooler pipe or the WCF100367 3.5 in upgrade. Made in the USA.
