Product Description

The restrictive factory air filters and air intake housings in your car are replaced with the more efficient AEM 21-677C 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, two larger AEM Dryflow synthetic washable air filters are used to introduce air into the system. Heat shields that are intended to lower intake air temperature and boost horsepower cover the air filters, which are housed in the original air box spaces. The intake tubes are made of mandrel-bent aluminum with a tough powder-coated gunmetal gray finish. This air intake system was designed to work with the engine's factory emissions control components, such as the crankcase vent tube and mass air flow sensors. The oil-free, synthetic filter media used to create the dual tapered cylinder-shaped AEM Dryflow air filters can be utilized for up to 100,000 miles before cleaning is necessary (depending on driving conditions). The air intake system is supported by AEM's Lifetime Limited Warranty and is simple to install using tools that are often found in homes. 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.
