The Banks Ram-Air out-flows and out-performs aFe and S&B when tested for Mass Air Flow. Denser, heavier air improves fuel economy since your engine has to work less hard to make the same horsepower. The Ram-Air system improves Mass Air Flow by 36% over to stock. That's a huge gain compared to S&B, and over twice the gain aFe produced.
Our Big-Ass Air Filter stands head and sholders above the rest offering the largest filter volume and surface area when compared to Stock, S&B, and aFe.
Your Ford Power Stroke is built to keep on trucking no matter what it faces. The last thing you want is to be stuck with reduced engine performance due to a clogged filter. The Ram-Air's Big-Ass filter boasts 116.7 in2 more filter surface area than its two closest competitors. That means more hauling, and less stopping between filter services.
When under load, your engine rocks from side-to-side. The Ram-Air system features unique billows that are positioned to allow engine movement. The XLPE intake tube slides under and through these billows to provide turbulence-free high-velocity airflow while maintaining a smooth bend into the turbo inlet.
The Banks Ram-Air system’s unique smooth tapered shape continues through the silicone billows and allows for turbulence-free airflow and maximum efficiency. With the least amount of restriction, pumping losses are reduced freeing up engine horsepower
The factory system has no aiflow management. Air is forced to take a difficult path through a restrictive filter while the OEM intake tube billows induce turbulence and reduce mass air flow.
aFe's intake tube necks down sharply right after the filter and has a portion of the intake tube plastic that goes across the back side of the filter. This induces turbulence to the air stream and a sharp bend before the turbo further reduces efficiency.
S&B's simple straight tube leaves performance potential on the table while its sharp bend before the turbo inlet reduces flow and performance.
