Show original supplier description
The AEM 21-548P Cold Air Intake System is engineered to provide a performance boost for the 2003-2006 Infiniti G35 with the 3.5L V6 engine. By replacing the factory's restrictive air intake and filter, this system allows for increased airflow into the engine, which can lead to gains in horsepower and torque. The system has been designed, tuned, and dyno-tested to ensure optimal performance for the specified G35 models. This cold air intake system utilizes AEM's Dryflow synthetic air filter, known for its filtration capabilities. The polished intake tubing not only contributes to performance but also adds a visual enhancement under the hood. The product is designed for a vehicle-specific fit, ensuring compatibility with the intended Infiniti G35 applications from 2003 to 2006.
