---tab Description--- Description This high-quality cast-aluminum Intake Manifold is a direct-fit replacement for the fragile OEM plastic manifold on 2011–2019 Ford 6.7L Super Duty trucks. Engineered for performance and durability, the 3.5" large-bore, two-piece design increases airflow, reduces intake turbulence, and provides a robust foundation for upgrades such as EGR delete, bigger turbos, intercooler plumbing, and race-level tuning. Built to withstand high temperatures and vibration, it’s ideal for towing, off-road, high-altitude, and tuned applications — yet fully suitable for daily drivers seeking improved response and longevity. Why Upgrade? Signs Your Factory Plastic Manifold is Failing:The OEM plastic manifold is prone to cracking under heat and boost pressure. It's time to upgrade if you are experiencing: Boost Leaks & Power Loss: Sluggish throttle or a hissing sound under the hood. Error Codes: Check Engine Light showing P0299 (underboost), P0234 (overboost), or erratic MAP sensor readings. Poor Running Conditions: Rough idle, misfires, or white/blue smoke during acceleration. Visible Damage: Warping or hairline cracks on the factory plastic housing. Fitment 2011–2019 Ford F-250 / F-350 / F-450 / F-550 Super Duty 6.7L Powerstroke. 2015–2016 kits include an external oil feed line in the package and require replacing the factory oil feed routing as supplied. Key Features High-Strength Cast Aluminum ConstructionDurable aluminum alloy resists heat fatigue and cracking common with OEM plastic manifolds; improves longevity under extreme conditions. 3.5" Large-Bore Flow PortsBigger, straighter flow paths reduce restriction and turbulence for faster turbo response and higher torque across the RPM band (larger than competing 3.0-inch designs). Two-Piece, Service-Friendly DesignEnables larger, more efficient runner geometry while keeping installation straightforward and OEM-compatible. Direct Bolt-On FitmentNo ECU recalibration required; replaces the factory manifold with supplied gaskets and hardware for a hassle-free swap. Finish & CompatibilityPowder-coated finish (black/red/silver) resists corrosion and looks premium; compatible with stock and most aftermarket induction and intercooler systems. End Plastic Problems: Permanent Reliability Over OEM Failure The factory plastic intake manifold on 2011-2019 6.7L Powerstroke trucks is a ticking time bomb. Over time, heat cycles and high boost pressure cause the OEM plastic to become brittle and eventually burst, leaving you stranded in "limp mode." SPELAB’s heavy-duty cast aluminum design eliminates this weak link forever. It’s not just an upgrade; it’s peace of mind for the life of your truck. Maintenance Friendly (Two-Piece Design) Our unique two-piece design does more than just flow better—it opens up your engine bay. By streamlining the manifold geometry, SPELAB provides significantly better access to fuel filters, oil lines, and other critical components. Spend less time struggling with...
