Designed specifically for 2001-2004 GM trucks, this high-flow Y-bridge replaces the factory restrictive components to improve airflow and boost engine performance. The kit features a durable, fabricated billet aluminum Y-bridge with a full 3-inch intake tract, which significantly increases airflow capacity—delivering up to 50% more than the OEM upper intake manifold and cold side charge pipe. This enhancement promotes better throttle response and quicker turbo spool-up, resulting in more responsive acceleration and increased power output. The kit includes a 14-gauge mandrel bent aluminum passenger side intercooler pipe, silicone boots, T-bolt clamps, and new O-ring flange gaskets for a secure, leak-free fit. An essential component is the FPRV block-off kit, which ensures proper clearance when installing larger diameter Y-bridges. The set also includes a map sensor seal and hold-down bracket for easy installation. Crafted with a durable, custom powder coat finish, the Wehrli Y-Bridge kit is built to withstand the harsh conditions of engine bay environments and is made in the USA. Please note, this kit is not recommended for use with S300 or S400 style turbochargers; if you plan to upgrade to these turbo types, consider Wehrli's S300 and S400 turbo kits. This product is EPA compliant and Prop 65 compliant, ensuring it meets regulatory standards. Designed for a precise fit on 2004 Chevrolet Silverado 2500 HD, Silverado 3500, and GMC Sierra 2500 HD models, this kit provides a reliable upgrade for serious enthusiasts looking to maximize their Duramax engine's performance and durability.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e50% more airflow than OEM upper intake manifold and cold side charge pipe\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e3-inch passenger side intercooler pipe made from 14-gauge mandrel bent aluminum\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes new O-ring flange gaskets for secure sealing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSilicone boots and stainless T-bolt clamps for durability and leak prevention\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMap sensor seal and hold-down bracket for easy installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDurable custom powder coat finish resists harsh engine bay conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFabricated billet aluminum Y-bridge for strength and reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes FPRV block-off kit for proper clearance with larger Y-bridge\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA for quality assurance\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD Base 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD LS 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2001\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2002\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2003\u003cbr\u003e\nChevrolet Silverado 2500 HD LT 2004\u003cbr\u003e\nChevrolet Silverado 2500 HD WT 2004\u003cbr\u003e\nChevrolet Silverado 3500 Base 2001\u003cbr\u003e\nChevrolet Silverado 3500 Base 2002\u003cbr\u003e\nChevrolet Silverado 3500 Base 2003\u003cbr\u003e\nChevrolet Silverado 3500 Base 2004\u003cbr\u003e\nChevrolet Silverado 3500 LS 2001\u003cbr\u003e\nChevrolet Silverado 3500 LS 2002\u003cbr\u003e\nChevrolet Silverado 3500 LS 2003\u003cbr\u003e\nChevrolet Silverado 3500 LS 2004\u003cbr\u003e\nChevrolet Silverado 3500 LT 2001\u003cbr\u003e\nChevrolet Silverado 3500 LT 2002\u003cbr\u003e\nChevrolet Silverado 3500 LT 2003\u003cbr\u003e\nChevrolet Silverado 3500 LT 2004\u003cbr\u003e\nChevrolet Silverado 3500 WT 2004\u003cbr\u003e\nGMC Sierra 2500 HD Base 2002\u003cbr\u003e\nGMC Sierra 2500 HD Base 2003\u003cbr\u003e\nGMC Sierra 2500 HD Base 2004\u003cbr\u003e\nGMC Sierra 2500 HD SL 2001\u003cbr\u003e\nGMC Sierra 2500 HD SL 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2001\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2003\u003cbr\u003e\nGMC Sierra 2500 HD SLE 2004\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2001\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2002\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2003\u003cbr\u003e\nGMC Sierra 2500 HD SLT 2004\u003cbr\u003e\nGMC Sierra 2500 HD WT 2003\u003cbr\u003e\nGMC Sierra 2500 HD WT 2004\u003cbr\u003e\nGMC Sierra 3500 Base 2002\u003cbr\u003e\nGMC Sierra 3500 Base 2003\u003cbr\u003e\nGMC Sierra 3500 Base 2004\u003cbr\u003e\nGMC Sierra 3500 SL 2001\u003cbr\u003e\nGMC Sierra 3500 SL 2002\u003cbr\u003e\nGMC Sierra 3500 SLE 2001\u003cbr\u003e\nGMC Sierra 3500 SLE 2002\u003cbr\u003e\nGMC Sierra 3500 SLE 2003\u003cbr\u003e\nGMC Sierra 3500 SLE 2004\u003cbr\u003e\nGMC Sierra 3500 SLT 2001\u003cbr\u003e\nGMC Sierra 3500 SLT 2002\u003cbr\u003e\nGMC Sierra 3500 SLT 2003\u003cbr\u003e\nGMC Sierra 3500 SLT 2004\u003cbr\u003e\nGMC Sierra 3500 WT 2004","brand":"Wehrli","offers":[{"title":"Default Title","offer_id":53958943310140,"sku":"wcfWCF100693-BB","price":898.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/66a9e6986fcb2ea961bbfad757c33925_0900dade-0f13-4a3e-a9fc-44dd78a3c1f3.jpg?v=1785736662","url":"https:\/\/necycleshop.com\/products\/wehrli-01-04-chevrolet-6-6l-lb7-duramax-3in-y-bridge-kit-bengal-blue","provider":"NE Cycle Shop","version":"1.0","type":"link"}
