The Wehrli WCF Y-Bridge Kit is a complete high-flow 3" replacement Y-bridge and cold-side charge pipe for 2001–2004 Duramax LB7 6.6L engines.

Kit includes 3" fabricated billet Y-bridge, mandrel-bent aluminum piping, silicone boots, clamps, new O-ring bridge gaskets, MAP sensor seal, hold-down bracket and an FPRV block-off for clearance, all finished in a durable powder coat and made in the USA.
