aFe MagnumFORCE Stage-2 Si Cold Air Intake with Pro 5R Filter for Select Toyota 2003-2011 (V6-4.0L)

Fits select 2003-2011 Toyota 4Runner, FJ Cruiser, and Tacoma models equipped with the V6-4.0L engine.

The aFe MagnumFORCE Stage-2 Si Cold Air Intake System replaces your restrictive factory air box and intake tract to deliver a massive 119% increase in airflow. This system features a sealed, rotomolded housing made from cross-linked polypropylene (XLPE) to isolate the filter from heat soak and reduce intake noise while pulling cooler, denser air from outside the engine compartment through a built-in ram air scoop.

At the heart of this system is the Pro 5R performance air filter, featuring five layers of progressively finer medical-grade cotton gauze media for maximum airflow and performance. The 360-degree radial flow filter is fully washable and reusable. The precision-engineered intake tube is CAD-designed to maximize airflow velocity, resulting in improved throttle response and power gains across the RPM range.
