Cold Air Intake for Nissan 350Z (2003-2006) 3.5L V6 Engine

Cold Air Intake System for Nissan 350Z 3.5L V6 (2003–2006)

Upgrade the performance, sound, and engine bay appearance of your 2003–2006 Nissan 350Z 3.5L V6 with this high-performance Cold Air Intake System, engineered to deliver measurable power gains and a more engaging driving experience.

Designed as a direct replacement for the restrictive factory air box, this intake system improves airflow efficiency by reducing intake resistance and isolating cooler air from engine heat. The result is stronger throttle response, improved acceleration, and up to a 10% increase in horsepower and torque, all while maintaining daily-driving reliability.

Constructed from T304 lightweight aluminum piping, the intake offers excellent heat resistance, durability, and long-term performance. The polished chrome finish enhances the engine bay with a clean, sporty appearance, while the high-flow red air filter maximizes air volume and filtration efficiency. This optimized airflow allows your VQ35 engine to breathe more freely, producing a deeper, more aggressive intake sound under acceleration.

The included washable and reusable air filter is designed for extended service intervals, requiring cleaning only every 50,000 miles under normal driving conditions, helping reduce long-term maintenance costs. Installation is straightforward and requires only basic hand tools, with most users completing the upgrade in under 60 minutes.

This cold air intake is compatible with both automatic and manual transmissions and is engineered to work seamlessly with the factory ECU. When installed correctly, it does not void your vehicle warranty. For optimal results, resetting the battery after installation allows the engine computer to relearn the increased airflow.
