Part # 21-547C

The restrictive factory air filter and air intake housing in your car are replaced by the more efficient AEM 21-547C Performance Cold Air Intake System to increase horsepower and torque. These Nissan 350Z cars were the focus of the design, tuning, and dyno testing of this air intake system. For exceptional air flow, filtration, and performance, air enters the system through a large AEM Dryflow synthetic washable air filter. To lower intake air temperature and boost horsepower, the air filter has been moved to the wheel well behind the front bumper on the driver's side. The intake tubing is made of mandrel-bent aluminum with a tough powder-coated gunmetal gray finish. The mass air flow sensor and engine breather pipe, among other factory emissions control components, were built into this air intake system. The oil-free, synthetic filter media used to create the tapered cylinder-shaped AEM Dryflow air filter can be used for up to 100,000 miles before cleaning is necessary (depending on driving conditions). The Lifetime Limited Warranty from AEM covers the air intake system. While some AEM air intakes are 50-state legal, some are not allowed for sale or use in California or other states that have adopted California emission rules. View the 21-547C vehicle applications to learn each vehicle's legal status. Replace the constrictive factory air filter, air intake tubing, and air box assembly with AEM's Performance Cold Air Intake Systems to increase your engine's power and acceleration.
