Wehrli 11-16 Chevrolet 6.6L LML Duramax High Flow Y-Bridge Kit - Illusion Purple

The Wehrli Custom Fabrication WCF100165-IP High-Flow Y-Bridge Kit replaces the restrictive OEM upper intake manifold with a precision CNC machined, cast aluminum intake bridge and a larger fabricated aluminum upper crossover intercooler pipe, increasing total airflow by 33% for improved engine performance. It retains the factory intake air heater grid for cold starts and includes a billet resonator plate. This kit is designed for bolt-on installation without tuning and is compatible with OEM throttle valve, EGR controls, and the lower passenger side intercooler pipe. Finished in Illusion Purple powder coat, it is manufactured in the USA.
