The aFe Magnum FORCE Stage‑2Si cold air intake for Toyota FJ Cruiser, Tacoma and 4Runner 4.0L replaces the stock airbox with a rotomolded plastic intake and sealed cover that draws cold air via a built‑in ram scoop. It uses a washable, reusable Pro 5R filter and claims up to 119% cfm flow gain over stock, improving throttle response while maintaining filtration; the system carries a 2‑year limited warranty.
