aFe 51-81172 Magnum FORCE Stage 2 Sealed Cold Air Intake System for Toyota Tundra
aFe Power - advanced FLOW engineering, Inc. is a manufacturer of high performance cold air intakes, air filters, fluid filters, exhaust systems, intake manifolds, intercoolers, turbochargers, programmers, differential covers, transmission pans and throttle body spacers for late model cars, trucks, and SUV's. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. Huge, high-flow conical air filters are the first step to increased airflow to the engine. Steel heat shields or molded plastic air boxes keep hot air out and fresh, cold air flowing to the filter. Velocity stacks and precision-designed intake tubes provide smooth, uninterrupted airflow to the turbo or throttle body. aFe Power offers different styles of air intake systems to meet the needs of your power hungry engine. For the largest possible performance gain replace the entire air box and intake tract with our STAGE 2 open element air intake system. If you want to maintain a factory appearance our STAGE 2 Si sealed air box provides quiet power. For a great value and easy installation our STAGE 1 air intake systems adds instant horsepower and torque. All of our cold air intake systems are manufactured and assembled at our Corona, California facility.
