A Genuinely Large Filter for Maximum Airflow

This intake system utilizes a large, 5-inch tall conical, 360-degree radial flow performance air filter with 5 layers of progressive, finer mesh cotton media, engineered for genuinely maximum airflow and performance rather than a modest bump over stock. That layered filter media design balances flow with real filtration, rather than sacrificing one for the other. A high-quality ABS plastic heat shield, developed specifically by aFe, blocks unwanted engine heat and eliminates heat soak that would otherwise rob the intake of some of its cooling benefit. It's the kind of upgrade that quietly does its job without ever needing a second thought.

Mandrel-Bent Tubing and a Purpose-Built Scoop

A high-quality, CAD-designed cross-linked polyethylene red intake scoop captures the coolest available air while maintaining a perfect fit, feeding into a one-piece 3-inch mandrel-bent, wrinkle-black powder-coated intake tube that directs unrestricted airflow from the large filter to the turbo for more horsepower and torque. All clamps, couplers, and hardware needed for installation are included, keeping the job hassle-free. It's a thoroughly engineered system where every component, from the filter media to the scoop to the tube, works together toward genuine flow gains. That's real, functional engineering, not just a marketing claim.
