Product Description

The aFe 51-82502 Magnum FORCE Stage-2 Si Cold Air Intake System with Pro DRY S filter is a direct-fit performance upgrade designed for 2005-2009 Toyota 4Runner and Lexus GX470 models powered by the 4.7-liter 2UZ-FE V8 engine. This sealed intake replaces the restrictive factory airbox with a purpose-built design that draws in a higher volume of cooler, denser air, improving engine breathing, throttle response, and overall performance. The included Pro DRY S synthetic air filter is oil-free, washable, and reusable - offering high airflow with minimal maintenance.

Featuring a CAD-designed, dyno-tuned roto-molded intake tube and durable sealed housing with a powder-coated aluminum cover, this intake system outflows the stock setup by approximately 66 % and can deliver dyno-proven gains of up to +20 HP and +20 lb-ft of torque under ideal conditions. Installation is straightforward with a bolt-on design that uses all factory mounting points, requiring no cutting or drilling. Keep in mind this intake is not currently CARB exempt and may not be legal for sale or use in California and other CARB states - always verify your local emissions regulations before purchase.
