Magnum FORCE Stage-2 Si Cold Air Intake

The aFe Power Magnum FORCE Stage-2 Si Cold Air Intake System is engineered to enhance the performance of your 2005-2009 Lexus GX470 or Toyota 4Runner equipped with the V8 4.7L gas engine. Key features include a heat-resistant XLPE housing, which is roto-molded for a precise fit and incorporates a unique one-piece design with a black powder-coated aluminum cover. This construction effectively shields the intake from warm engine bay air, ensuring a cooler air charge. The system utilizes a 6" tall, 360-degree inverted top Pro 5R air filter. This washable and reusable filter is made from 5 layers of progressive, oiled media, offering excellent filtration (tested at 98.6% efficiency) and high airflow, even as it accumulates dirt. The accompanying roto-molded intake tube is CAD-designed and dyno-tuned to maximize power gains and ensure a perfect fit. An auxiliary air inlet is also integrated into the sealed housing to further increase air volume for enhanced performance and throttle response. Performance testing on a 2005-2009 Lexus GX 470 V8-4.7L demonstrated gains of up to 20 horsepower and 20 lbs. x ft. of torque, while outflowing the factory intake by 66%. The system achieved a measured flow of 190 CFM @ 1.5" H2O. It's important to note that this intake system is not CARB exempt and is not legal for sale or use in California on vehicles registered with the California Department of Motor Vehicles.
