Cold Air Intake for 2003-2006 Infiniti G35/FX35 & Nissan 350Z | 3.5L V6 VQ35DE Performance Upgrade

Unleash the True Potential of Your VQ35DE Engine

Imagine pressing the accelerator and feeling an immediate, exhilarating response—the kind of raw power that the legendary VQ35DE engine was born to deliver. Whether you're driving the track-proven Nissan 350Z, the sophisticated Infiniti G35, or the commanding FX35, your 3.5L V6 deserves to breathe freely and perform at its peak.

This premium cold air intake system transforms your driving experience by replacing the restrictive factory air box with a performance-engineered solution designed specifically for 2003-2006 models equipped with the VQ35DE engine. It's not just an upgrade—it's the performance unlock your vehicle has been waiting for.

Experience Performance You Can Feel

From the moment you install this cold air intake, you'll notice the difference. Throttle response becomes sharper and more immediate, giving you the confidence to merge, pass, and accelerate with authority. The VQ35DE engine, already renowned for its smooth power delivery and high-revving character, gains up to 10% more horsepower and torque. That means quicker acceleration, better passing power, and a more engaging drive every single time you get behind the wheel.

The secret lies in maximizing airflow. By drawing cooler, denser air directly into your engine and eliminating the restrictive factory intake tube, this system allows your VQ35DE to inhale more freely. More air means more efficient combustion, which translates to improved fuel economy alongside those impressive power gains. You'll spend less time at the pump while enjoying a more spirited, responsive ride.

Built to Last, Engineered to Perform

Constructed from lightweight T304 aluminum piping, this cold air intake combines durability with performance. The premium materials resist corrosion and heat, ensuring your investment continues delivering results for years to come. The high-flow, washable filter provides exceptional filtration while maintaining optimal airflow—a critical balance that protects your engine while unleashing its power.

Unlike disposable factory filters that require frequent replacement, this washable filter only needs cleaning every 50,000 miles under normal driving conditions. That means less maintenance hassle and significant savings over time. Simply clean, re-oil, and reinstall—it's that easy to maintain peak performance.

Sound That Matches the Performance

Listen to your engine come alive with a deeper, more aggressive tone that announces your presence. The improved airflow through the stock manifold system creates a sporty, throaty sound that reminds you—and everyone around you—that you're driving a performance machine. It's the perfect soundtrack for spirited drives, whether you're carving canyons in your 350Z or cruising in your G35.

Simple Installation, Professional Results

You don't need to be a master mechanic to transform your vehicle's performance. This cold air intake installs in less than 60 minutes using basic hand tools like screwdrivers and socket wrenches. Most customers complete the installation themselves by following straightforward instructions or helpful YouTube videos specific to their vehicle.

After installation, simply disconnect your battery terminal for a few seconds to reset your engine computer. This allows the ECU to recalibrate and optimize performance for the increased airflow. The entire process is warranty-friendly—this upgrade will not void your vehicle's warranty, giving you peace of mind alongside improved performance.

The Perfect Upgrade for Enthusiasts

Whether you're a dedicated car enthusiast looking to extract every bit of performance from your VQ35DE engine or simply want a more engaging daily driving experience, this cold air intake delivers measurable results. Better acceleration, improved fuel efficiency, enhanced engine sound, and a sportier appearance under the hood—all in one comprehensive upgrade.
