Product information for 3" Y-Bridge & Intercooler Pipe Kit Hot & Cold Side for 2011-2016 Chevy/GMC 2500HD/3500HD 6.6L Duramax LML | SPELAB - Black

---tab Description--- Description You’ve already made the smartest upgrade possible for your 2011-2016 6.6L LML Duramax by ditching the failure-prone factory CP4 pump for a reliable CP3. But if you are still pushing air through the factory 2.5-inch plastic intercooler pipes, you are suffocating your engine and leaving serious horsepower on the table. Eliminate the Plastic Weak Links.The factory LML intake system is riddled with bottlenecks. The plastic turbo resonator is notorious for cracking and leaking under high heat, and the thin rubber hoses expand and blow off when you turn up the boost. Whether you are running a heavy 5th-wheel up a grade or flashing a high-horsepower tune, these factory flaws lead to soaring Exhaust Gas Temperatures (EGTs) and sluggish throttle response. The SPELAB 3" Airflow Solution.Built specifically for CP3-converted trucks, our Y-Bridge, Hot Side, and Cold Side Intercooler Pipe Bundle replaces the restrictive factory plumbing with massive 3-inch, mandrel-bent 6061 aluminum tubing. By optimizing the geometry and shortening the air path, this kit increases airflow by a staggering 86.4%. The result? Faster turbo spool, drastically lower EGTs, and the bulletproof reliability you need to tow heavier and tune harder. Fitment 2011-2016 Chevrolet Silverado 2500HD / 3500HD 6.6L Duramax LML 2011-2016 GMC Sierra 2500HD / 3500HD 6.6L Duramax LML Compatibility Notes: CP3 CONVERSION ONLY: This Y-Bridge kit is engineered exclusively for LML trucks that have completed a CP3 High-Pressure Fuel Pump conversion. NOT COMPATIBLE: It will NOT fit trucks equipped with the factory CP4 fuel pump. Please verify your fuel system before ordering. Key Features Massive 86.4% Airflow IncreaseUpgrades the restrictive 2.5" factory piping to massive 3" mandrel-bent aluminum tubing. Delivers a significantly higher volume of cold, dense air to your engine, resulting in instant turbo spool and sharper throttle response. Engineered for CP3 ConversionsSpecifically CAD-designed to clear the fuel lines and geometry of a CP3 high-pressure fuel pump setup. Provides a perfect, drop-in fit for high-horsepower builds without the hassle of custom fabrication. Lower EGTs for Heavy TowingA smoother, larger air path means less pressure drop and lower Exhaust Gas Temperatures. Allows you to tow heavy loads up steep grades in summer heat with zero power fade and maximum engine safety. Blowout-Proof ConnectionsIncludes upgraded 5-ply silicone boots and heavy-duty stainless steel T-bolt clamps. Grips tighter than standard worm-gear clamps, ensuring your boots never blow off, even under extreme high-boost tuning applications. CNC Flanges & TIG WeldedFeatures precision CNC-machined flanges mated with masterful TIG welding. Guarantees a perfectly flat, leak-free seal against the engine block that will not warp or deform under thermal stress. Bulletproof ReliabilityReplaces the fragile factory plastic turbo resonator and weak rubber hoses with heat-resistant 6061 aluminum. Eliminates the most common sources of boost leaks, keeping you on the road and out of the shop. Specification Fuel System Requirement CP3 Conversion REQUIRED (Will NOT fit CP4) Material 6061 Aluminum (Mandrel-Bent) Tubing Diameter 3.0 Inches (Up from 2.5" OEM) Boot Material 5-Ply Reinforced High-Temp Silicone Gross Weight 7.47 kg (16.4 lbs) ---tab FAQ--- FAQ Q: Will this fit my stock 2015 LML?A: No. If your truck still has the factory CP4 high-pressure fuel pump, this kit will not fit. It is designed specifically to clear the geometry of an aftermarket CP3 fuel pump conversion. Q: I see some competitors use a 1-piece Y-Bridge. Why is this a 2-piece design?A: The LML engine bay is notoriously cramped. While a 1-piece design looks nice on a workbench, it can be a nightmare to install. Our 2-piece interlocking design gives you the micro-adjustability needed to snake the plumbing into place and perfectly align the flanges without fighting the firewall, saving you hours of installation frustration. Q: Do I need a custom tune to run this kit?A: Yes. Because this is a high-performance part designed for CP3-converted vehicles (which already require tuning), and because it alters factory emissions airflow routing, custom ECU tuning is required for your truck to run correctly and remain code-free. Q: Are the silicone boots better than stock?A: Drastically better. Factory rubber hoses degrade with oil vapor and swell under boost. Our 5-ply silicone couplers are reinforced to handle extreme heat and pressure without deforming, ensuring your boost actually makes it into the engine. Q: Is this product street-legal in California?A: No. This product does not have a CARB (California Air Resources Board) Exemption Order. It is strictly for off-road or organized racing use only. ---tab Shipping & Returns--- Fast Shipping Policy Your order will be dispatched within 1-2 business days, and the package will arrive within your order's estimated date.
