The AEM 21-793C cold air intake replaces the restrictive factory air filter and intake housing on specific Nissan Maxima models with a system engineered, tuned, and dyno-tested for horsepower and torque gains. Air is drawn through an oversized AEM Dryflow synthetic washable filter placed in the original air box location and shielded from underhood heat, while a mandrel-bent aluminum tube finished in gunmetal gray powder coat routes air to the throttle body. The system retains the factory mass air flow sensor and engine vent hose for an easy installation with common hand tools.
