The AEM 21-818C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Nissan Sentra models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter. This oil-less filter is designed to have outstanding air flow, filtration and performance. It is then relocated to the driver-side wheel well to take advantage of cooler air temperatures. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Innovation has always been AEM's core competency. As J.C. would say "if you can't make something better, why make it all?" This "make it better" drive combined with our commitment to the sport compact market continues to distinguish AEM from the many company's offering "Me Too" copycat products. Our innovations are inspired by a passion for engineering excellence, being there and getting our hands dirty, the only way to really understand technology enough to make it better. The company continues to lead the way with innovative products that push the envelope of what is possible.
