Product Description

The Mishimoto MMAI-350Z-03H performance cold air intake is a direct-fit upgrade designed specifically for the 2003-2006 Nissan 350Z equipped with the VQ35DE 3.5 L V6 engine. This intake replaces the restrictive stock airbox with a high-flow aluminum intake pipe and an oiled performance filter that increases airflow while maintaining proper MAF response and engine tune safety. A dedicated powder-coated heat shield seals to the front inlet duct to draw cooler air from ahead of the vehicle, helping reduce intake air temperatures under spirited driving.

Installation is straightforward and typically takes less than an hour with common hand tools. The system delivers aggressive induction sound and dyno-proven gains of up to approximately 10 wheel horsepower and 13 foot-pounds of torque without requiring a tune on a stock engine. Compatible with the stock radiator and MAF housing, the MMAI-350Z-03H maintains OEM-like drivability while adding performance and throttle response. Covered by Mishimoto's Lifetime Warranty, this intake offers an effective balance of performance, reliability, and daily-drivable comfort.
