Product Description

The Volant 12635 Pro-5 Closed Box Cold Air Intake is a performance-oriented upgrade designed specifically for the Nissan 350Z equipped with the 3.5L V6 (2003-2006). Replacing the stock air intake with a larger, closed-box system, this intake increases airflow efficiency while shielding the filter from engine bay heat. This helps deliver a denser, cooler air charge for improved horsepower, torque, and throttle response.

Featuring a reusable MaxFlow 5 oiled cotton gauze filter, heat-resistant ducts, and a high-velocity venturi adapter, this kit enhances performance without complicated modifications. Installation is straightforward with OEM-style mounting points, making it an excellent first modification for enthusiasts looking to boost engine breathing and acceleration on 350Z models. A CARB Executive Order (D-526-4) applies for this application, and standard Emissions laws should be confirmed locally.
