Product Description

The K&N 57-6013 Cold Air Intake System is engineered to replace the restrictive factory air intake components in the 2003-2006 Nissan 350Z equipped with the 3.5L V6 VQ35DE engine. This performance intake system is designed to increase horsepower and torque by improving airflow to the engine.

Constructed from high-density cross-linked polyethylene (HDPE), the intake tube is rotationally-molded for optimal airflow.

A custom heat shield is provided to protect the intake air from the high temperatures of the engine bay, ensuring cooler, denser air enters the engine for improved combustion efficiency.

Installation is straightforward and can typically be completed in under 60 minutes using simple hand tools. The K&N 57-6013 is backed by a No-Hassle Lifetime Limited Warranty and is emissions-legal in all 50 states, featuring CARB E.O. Number D-269-28.
