The Wagler WCPC6622.3 Street Intake Manifold is built to eliminate that restriction entirely, replacing the factory piece with a cast one-piece design engineered for improved airflow and real horsepower gains. This isn't a bolt-on upgrade for a stock truck, it's purpose built for guys running aftermarket turbo setups who need an intake that can keep up with serious boost. The intake neck is machined to accept a 3.5 inch V-band connection standard, giving you a secure, reliable seal even in the most extreme applications, with a Vanjen option available if your build calls for it. Wagler specifically designed this manifold to pair well with their own T4 Twisted Pedestal setup, making it a natural fit for anyone already building around Wagler's turbo mounting components. If you're chasing serious power numbers on your Duramax and the factory y-bridge is holding back your setup, this manifold removes that limitation for good. It's a build-specific part for owners who know exactly what they're working toward.\u003c\/p\u003e\n\u003ch4\u003eCast Construction Engineered To Replace The Factory Y-Bridge\u003c\/h4\u003e\n\u003cp\u003eThe Wagler WCPC6622.3 Street Intake Manifold is engineered for 2004.5-2010 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with the 6.6L Duramax LLY, LBZ, or LMM engine. This aftermarket intake manifold fully replaces the factory y-bridge with a cast one-piece design intended to improve airflow and support increased horsepower output. The intake neck is precision machined to accept a 3.5 inch V-band connection as the standard configuration, with a Vanjen fitment available upon special request for builds that require it. This manifold is specifically designed around aftermarket turbocharger applications and is not compatible with the OEM turbocharger, making it a component intended for trucks already running or planning an aftermarket turbo setup such as Wagler's own T4 Twisted Pedestal. For sealing, Wagler specifies McMaster-Carr O-ring part number 9396K175, sized at 4.250 ID by 4.4375 by .103 inch thick, for owners who need a replacement down the line. Given its extreme-application design and OEM turbo incompatibility, this manifold is best suited for a dedicated performance build rather than a factory-turbo daily driver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2004.5, 2005, 2006, 2007, 2008, 2009, 2010 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LLY\/LBZ\/LMM\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNot compatible with the OEM turbocharger, requires aftermarket turbo setup\u003c\/li\u003e\n\u003cli\u003eIntake neck machined for 3.5\" V-band standard, Vanjen available upon request\u003c\/li\u003e\n\u003cli\u003eReplacement O-ring: McMaster-Carr #9396K175, 4.250 ID x 4.4375 x .103 thick\u003c\/li\u003e\n\u003cli\u003ePairs well with Wagler T4 Twisted Pedestal turbo mounting setup\u003c\/li\u003e\n\u003cli\u003eIntended for performance\/race applications, not a stock-turbo bolt-on\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wagler Competition Products","offers":[{"title":"Default Title","offer_id":54605560906012,"sku":"WCPC6622.3","price":1270.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/image_26.webp?v=1790275113","url":"https:\/\/www.alligatorperformance.com\/products\/wagler-wcpc6622-3-duramax-street-intake-2004-5-2010-gm-sierra-silverado-2500hd-3500hd-duramax-lly-lbz-lmm","provider":"Alligator Performance","version":"1.0","type":"link"}
