6.7L Powerstroke Cast Aluminum Intake Manifold

The SPELAB 6.7L Powerstroke Cast Aluminum Intake Manifold is engineered as a robust replacement for the factory plastic manifold, notorious for cracking and causing the P200C engine code. Constructed from heat-treated cast aluminum, this manifold is rated to withstand over 400°F and 50+ PSI of boost, making it significantly stronger and more durable than the OEM composite plastic. This performance upgrade features a true 3.5-inch internal diameter, eliminating the restrictive choke point found in the stock manifold's approximately 2.15"-2.5" internal narrowing. This design increases effective flow volume by over 45%, leading to smoother airflow, reduced Exhaust Gas Temperatures (EGTs), and quicker turbo spool. It serves as a foundation for high-flow piping kits and EGR delete configurations. The manifold retains the factory MAP sensor location and geometry, ensuring it works seamlessly with your stock calibration without requiring an ECU tune for basic installation. However, a professional tune is recommended to maximize performance gains, especially when combined with turbo or EGR delete modifications. The manifold is available in Black, Red, or Silver with a premium powder-coated finish for corrosion resistance. Fitment is for 2011-2019 Ford F-250/F-350 Super Duty 6.7L Powerstroke models. A specific note for 2015-2016 models indicates that an external oil feed line is included and requires replacing the factory oil feed routing. Installation is described as manageable for a competent DIYer with basic tools, but professional installation is recommended for more complex related upgrades.
