Cold Air Intake for Nissan Altima (2002-2006) / Nissan Murano (2003-2006) 3.5L V6 Engine

Maximize Throttle Response and Induction Sound for the Nissan VQ35DE Engine

Who It’s For: Designed specifically for 2002-2006 Nissan Altima and Murano owners running the 3.5L V6, known to enthusiasts as the VQ35DE engine. This is for the driver who wants to bridge the gap between a daily commuter and a performance-oriented machine.

The Problem: The stock intake system on the VQ35DE is built for silence, not flow. Between the restrictive corrugated rubber bellows and the baffled plastic air box, the engine is forced to fight for air. This design traps heat under the hood and creates turbulence, resulting in a laggy throttle and a muted engine note that doesn’t do this V6 justice.

The Solution: This Cold Air Intake replaces the factory restrictions with mandrel-bent T304 lightweight aluminum piping. We engineered this system to provide a direct, smooth path for high-velocity air to reach the manifold. By swapping the paper filter for a high-flow washable element, we optimize the air-to-fuel ratio and give the VQ35DE the aggressive, throaty growl it was designed to have.

Why This is the Ultimate Upgrade

• Enhanced Power Band: Improves horsepower and torque by up to 10% by delivering cooler, denser air compared to the heat-soaked factory box.
• Premium T304 Construction: The lightweight aluminum piping is built to dissipate heat faster than OEM plastic and will not crack or degrade over time.
• Serviceable High-Flow Filter: The included washable filter provides superior filtration and only requires maintenance every 50,000 miles under standard driving conditions.

The Performance Promise

Buy with confidence. This kit is designed for a "no-tune-required" installation, meaning you can bolt it on in under 60 minutes with basic hand tools and head straight to the road. It is a direct replacement for the factory air box and will not void your vehicle’s warranty. For the best results, we recommend a brief battery reset after installation to allow the ECU to recalibrate for the increased airflow.
