{"product_id":"stage-3-high-flow-intake-bundle-kit","title":"Stage 3 High Flow Intake Bundle Kit","description":"The Wehrli Custom Fabrication Stage 3 High Flow Intake Bundle Kit is engineered for the 2006-2007 LBZ 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500\/3500 HD. This Stage 3 kit integrates the popular Stage 2 High Flow Bundle with a 3-inch Stainless Steel Down Pipe to significantly increase air and exhaust flow for improved efficiency, throttle response, and turbo spool up.\n\nThe air intake system replaces restrictive factory plastic parts with a high-flow fabricated intake pipe, a large 4.8-inch intake horn (providing a 20% airflow improvement over stock), and an airbox enclosure with a dry filter and Outerwears pre-filter cover. Constructed from 14-gauge aluminum with smooth, aerodynamic bends, the 4-inch piping enhances airflow velocity and volume.\n\nPost-turbo, the kit upgrades the factory 2.5-inch hot-side intercooler pipe and the leak-prone plastic cold-side pipe with heavy-duty 3-inch (hot-side) and 3.5-inch (cold-side) LBZ Intercooler Pipes. These pipes are made in the USA from 14-gauge aluminum and feature smooth, mandrel bends for optimized flow. The 3.5-inch passenger side pipe offers a 47% airflow improvement over stock. The Y-Bridge Kit, a critical component, replaces the OEM upper intake manifold with a high-flow, bolt-together 3-inch design that provides a secure sealing surface and prevents blow-apart failures common in high-performance applications.\n\nAll components are finished in a choice of WCFab's custom powder coat colors. It is compatible with stock trucks without needing other modifications or upgrades. Note: CSF Aftermarket intercoolers require modification or grinding of the intercooler outlet lip for installation.","brand":"Wehrli Custom Fabrication","offers":[{"title":"Default Title","offer_id":52866624520504,"sku":"WCF100503","price":2630.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687410001.jpg?v=1787909382","url":"https:\/\/store.motormia.co\/products\/stage-3-high-flow-intake-bundle-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
