aFe MagnumFORCE Intake Stage-2 Si Pro DRY S 05-09 Lexus GX 470/Toyota 4Runner V8 4.7L *RACE ONLY*
This Stage-2 Sealed cold air intake resulted in 20 horsepower, 20 lbs. x ft. torque and outflowed the factory intake by 66% on the 2005-2009 Lexus GX 470 V8-4.7L.
Fully enclosed in a heat-shielding roto-molded plastic housing; this air intake system features a washable/reusable conical air filter that improves airflow for increased horsepower and torque. The housing also features an auxiliary inlet for better airflow as well as an attractive black powder-coated aluminum cover that provides ready access to the filter for servicing. This intake system also features a heat-insulating roto-molded plastic tube that replaces the stock intake tract and directs increased airflow with improved volumetric efficiency for maximum performance. The filter is constructed using polyurethane for long life and multiple cleaning cycles.
Unique One-Piece Housing:
A completely sealed roto-molded plastic housing with a black powder-coated aluminum cover keeps warm engine air out and allows for a cooler, fresher, denser air intake charge.
Roto-Molded Tube:
This System uses a CAD designed, dyno-tuned, roto-molded intake tube to achieve maximum power gains while maintaining a perfect fit.
Auxiliary Air Inlet:
The sealed housing features an auxiliary air inlet that allows for increased air volume into the intake for increased performance and improved throttle response.
6" Tall 360 Degree Inverted Top Air Filter:
This filter features 3-layers of progressively finer mesh synthetic "oil-free" media to provide maximum flow with excellent filtration. The progressive layering of media allows the filter to flow at high levels even when dirty. The Pro DRY S non-oiled synthetic air filter requires no oils for cleaning for maximum convenience.
Proven Results:
After a rigorous design and testing phase, the results are in. The Magnum FORCE Stage-2 Si intake system outflowed the factory intake by 66% and resulted in 20 additional horsepower and 20 lbs. x ft. torque max gain.
Hassle-Free Installation:
aFe has developed this intake to provide a hassle-free installation utilizing all factory mounting locations and includes all hardware.
