Intake Manifold for 2008-2010 Ford F250 F350 6.4L Powerstroke | SPELAB

Aluminum Intake Horn Upgrade for 2008–2010 6.4L Powerstroke

Your 2008-2010 Ford 6.4L Powerstroke is a torque monster, but it left the factory with a fatal flaw. The OEM intake horn is made of cheap plastic. Over time, under extreme engine bay heat and high boost pressure, this plastic becomes brittle and cracks at the base.

The Danger of "Engine Dusting"

When that factory plastic cracks, it creates a massive vacuum leak that bypasses your air filter. Your engine begins sucking in unfiltered, abrasive dust and dirt directly into the cylinders and turbocharger. This "dusting" causes irreversible, catastrophic internal engine wear that can cost you upwards of $10,000 to repair.

Bulletproof Your Engine with SPELAB.

The SPELAB Aluminum Intake Horn is the ultimate insurance policy for your 6.4L. Cast and precision CNC-machined from aerospace-grade 6061-T6 aluminum, it completely eliminates the risk of cracking. But we didn't just fix the flaw—we improved the flow. By smoothing out the internal diameter, this horn reduces airflow turbulence, delivering faster turbo spooling, instant throttle response, and the massive air volume required to support high-horsepower tunes.

6.4L Powerstroke Intake Manifold FAQs

Q: Why is the factory plastic horn so dangerous to my engine?
A: The OEM plastic becomes brittle from constant heat cycling. When it eventually cracks at the base, it acts as a vacuum, pulling unfiltered, abrasive dirt directly into your engine cylinders. This destroys piston rings and cylinder walls—a devastating failure known as "dusting."

Q: Do I need a custom ECU tune after installing this intake horn?
A: No, this intake horn can be safely installed on a completely stock truck without requiring an ECU reflash. However, because it flows air much more efficiently, it perfectly complements trucks that are already tuned.

Q: Does this kit retain the factory CCV connection?
A: Yes, the SPELAB intake horn is designed with the exact ports required to retain your factory Crankcase Ventilation (CCV) setup and intake heater connections (if applicable).

Q: Is the installation difficult?
A: Installation is highly straightforward. It utilizes the factory mounting locations and comes complete with all required gaskets, O-rings, and bolts. It can be installed in your driveway with standard hand tools.

Will this intake horn fit all 6.4L Powerstroke trucks?

It is specifically listed for 2008, 2009 and 2010 Ford F-250 and F-350 Super Duty models equipped with the 6.4L Powerstroke diesel engine. Confirm the vehicle year, model and existing intake configuration before ordering.

What colors are available?

The intake horn is available in Black, Red and Silver. Select the required finish from the product options before adding it to your cart.

What is included in the package?

The package includes one aluminum intake horn in the selected color, the required O-rings and gaskets, mounting hardware and the components shown in the product images.

Can this intake horn be used on a tuned truck?

Yes. The intake horn can be used on a stock truck without an ECU reflash and is also designed to complement tuned trucks, upgraded injectors and upgraded turbo applications.

Is this product suitable for towing applications?

Yes. Its aluminum construction is intended for trucks exposed to sustained engine-bay heat and boost pressure during towing and other demanding operating conditions.

Installation

Before Installation

• Allow the engine to cool completely before working in the engine bay.
• Disconnect both batteries before removing intake components or electrical connections.
• Confirm the vehicle year, model and 6.4L Powerstroke engine application.
• Compare the supplied intake horn, O-rings, gaskets and hardware with the package contents.
• Inspect the factory intake connections and surrounding components for damage or contamination.
• Prepare standard hand tools and keep the work area clean to prevent debris from entering the intake system.

Installation Overview

1. Disconnect both batteries and allow the engine to cool.
2. Remove or reposition the components required to access the factory intake horn.
3. Disconnect the applicable intake, CCV and electrical connections from the factory component.
4. Remove the factory intake horn and inspect the mounting and sealing surfaces.
5. Clean the sealing surfaces without allowing dirt or loose material to enter the intake.
6. Position the supplied O-rings or gaskets and install the SPELAB aluminum intake horn.
7. Install the supplied mounting hardware and tighten the fasteners evenly.
