Air Intake Kit For Nissan XTerra/ Pathfinder/ Frontier (2005-2015) with 4.0L Engine

Stop letting your VQ40DE breathe through a restrictive plastic straw and finally give your Nissan the airflow it needs for better throttle response and a deeper, more aggressive engine note.

Performance High-Flow Air Intake Kit for Nissan Frontier, Xterra, and Pathfinder (VQ40DE 4.0L V6)

If you own a second-gen Frontier, Xterra, or Pathfinder, you know the VQ40DE is a legendary workhorse, but the factory air box is a major bottleneck. Designed for silence rather than efficiency, the stock setup uses corrugated plastic tubing that creates massive air turbulence. This kit replaces that restrictive assembly with smooth-bore T304 lightweight aluminum piping, allowing your engine to pull in a higher volume of oxygen-rich air with much less effort.

The shared F-Alpha platform across these three models means they all suffer from the same "lazy" throttle feel from the factory. By optimizing the airflow path to the stock manifold, this upgrade improves combustion efficiency and delivers a noticeable "wake-up" call to your V6. Whether you're climbing a trail in an Xterra or towing with your Pathfinder, you’ll appreciate the extra grunt and the distinct, throaty growl that only a high-flow intake can provide.

This isn't just about sound; it's about longevity and efficiency. The included high-flow filter is washable and reusable, meaning you can stop buying those paper disposables every few oil changes. It's a bolt-on solution that respects your engine's reliability while providing the performance edge that Nissan's 4.0L platform is truly capable of.

Why You Need This Upgrade

• Increased Power Density: Boosts horsepower and torque by up to 10% by reducing intake restriction.
• Sharper Throttle Response: Eliminates the "laggy" feel of the factory corrugated tube for more immediate acceleration.
• High-Durability Construction: T304 lightweight aluminum piping resists heat soak and won't crack like OEM plastic.
• Extended Service Intervals: The washable high-flow filter only needs cleaning every 50,000 miles under normal conditions.
• Aggressive Acoustics: Replaces the muffled factory sound with a deep, sporty tone during wide-open throttle.

Installation Notes

Installation is straightforward and requires only basic hand tools like a socket set and screwdrivers. No drilling or permanent modification is required. Pro Tip: Always disconnect your battery terminal during the install. We recommend leaving it disconnected for a few minutes after completion to force the ECU to reset its fuel trims and "learn" the new, increased airflow parameters for maximum gains.
