Cold Air Intake for Infiniti FX35 G35 (2003-2006) 3.5L Engine

Optimize Airflow and Induction Sound for your Infiniti VQ35DE FX35 & G35

Who It’s For: Designed specifically for 2003-2006 Infiniti FX35 and G35 owners running the legendary VQ35DE engine who want to improve throttle mapping and engine soundtrack.

The Problem: From the factory, the VQ35DE is choked by a restrictive plastic air box and a corrugated "accordion-style" intake hose. This design is focused on noise reduction rather than flow efficiency, creating air turbulence that slows down throttle response and masks the engine’s natural exhaust note.

The Solution: We engineered this intake system with mandrel-bent T304 aluminum piping to provide a smooth, high-velocity path for oxygen to reach the manifold. By eliminating the factory baffles, we allow the engine to breathe deeper, resulting in more consistent power delivery and a distinct, throaty growl under load.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Dyno-tested to improve horsepower and torque by up to 10% by reducing pumping losses found in the stock assembly.
• T304 Aluminum Construction: Lightweight aluminum piping resists heat soak better than thinner metals and provides a clean, show-quality look under the hood.
• Serviceable High-Flow Filter: The included synthetic pleated filter is washable and reusable, engineered to protect your VQ35DE for up to 50,000 miles between cleanings.

The Performance Promise

Professional Insight: When installing this kit, I always recommend disconnecting the negative battery terminal for about 10 minutes. This forces the ECU to reset its long-term fuel trims and “re-learn” the increased air volume from your new high-flow system. You’ll notice the difference in throttle crispness almost immediately.
