The AEM 22-680C Performance Air Intake System is a free-flowing, mandrel-bent aluminum tube air induction system designed to replace the restrictive factory air filter, air intake tubing and air inlet duct while retaining the factory air box on some Toyota Tundra V8 models. The air intake system comes with a replacement AEM high-flow air filter, an AEM air accelerator inlet duct and a free-flowing aluminum intake tube that easily connects to your vehicles factory air box and engine throttle body to dramatically increase air flow into your engine. With more air flowing through the custom-tuned intake system you experience more horsepower and acceleration throughout the engines RPM range. The intake tube is finished with an attractive and durable gunmetal gray powder-coating that provides a clean, high-performance look under the hood. The AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before servicing is needed (depending on driving conditions). The air intake is designed for easy installation and simply requires one screwdriver and a ratchet set to do the job. The intake system accommodates your vehicles factory emissions control devices including the mass air sensor and vacuum lines. This air intake system is street legal in all 50 US states and comes with AEM's Lifetime Limited Warranty.
