Description

The STILLEN Gen 2 Air Intake Kit (part number 402843DF) is engineered to boost performance for select Infiniti vehicles, including the G35, G37, Q40, Q60, and EX35 models from the years 2007-2009. This cold air intake design incorporates urethane heat shields to ensure consistent performance by preventing hot engine compartment air from entering the intake tract. It draws air from behind the grille, optimizing performance. It offers improved acceleration with a claimed gain of 6WHP and 5WTQ, enhanced throttle response, and potentially better mileage per gallon due to improved airflow. The polished aluminum tubes and the overall design also contribute to an enhanced underhood appearance. This intake system is compatible with both Rear-Wheel Drive (RWD) and All-Wheel Drive (AWD) models. However, please note that this product is not for sale in California.
