SPE Motorsport 11-26 6.7L Powerstroke Big AF Intake

Shipping January 2026!

Big chargers require big airflow. The SPE Motorsport Big AF Intake was built for high–air demand turbo setups where the standard cold-air layout cannot keep up. Whether you're running an S300,S400 Emperor turbo system or even a VGT charger, the Big AF Intake delivers the airflow volume, consistency, and MAF stability required for serious power.

At the core of the system is a massive billet MAF housing designed for smooth, accurate airflow and consistent tuning data. Paired with a full 5-inch ID intake tube and an oversized 6-inch filter, this system provides significantly more air than any stock-style intake paired with a factory style lower adapter. The result is reduced restriction, improved turbo efficiency, and stable MAF scaling for tuners pushing these platforms to their limit.

Modular by Design
The Big AF Intake was created to integrate directly into the SPE ecosystem. It works with our S400,S300 and vgt turbo configurations, but all setups require the corresponding SPE intake piping kit for proper fitment and routing. This modular approach allows you to build your system in stages and expand as your setup evolves, without wasting components or re-buying parts.

Performance and Fitment
Every component is engineered to maximize flow and minimize turbulence from the filter all the way to the compressor inlet. The billet MAF housing ensures accurate sensor placement and reliable scaling. The large-diameter tube and high-flow filter provide the air volume big-frame turbos need, without compromising drivability or tune stability. The setup stays engine mounted. So no more crakced brackets. Installation is straightforward with factory-style connections and all hardware included.
