Cold Air Intake for Infinti QX56 (2004-2010) 5.6L Engine

Maximize Airflow and V8 Growl on your 2004-2010 Infiniti QX56 VK56DE

Who It’s For: Designed specifically for Infiniti QX56 owners running the VK56DE V8 engine who want more aggressive acceleration and a throatier engine note during wide-open throttle.

The Problem: The VK56DE is a powerhouse, but the factory intake system is choked by restrictive plastic baffles and a closed-box design meant to prioritize silence over performance. This setup creates turbulence and allows for heat soak, which pulls timing and robs your heavy-duty SUV of its natural torque.

The Solution: This high-flow system replaces the stock restrictions with a mandrel-bent intake tube and a high-velocity filter. We engineered this kit to isolate the air charge from the engine bay heat, ensuring your VK56DE breathes cooler, denser air for improved combustion efficiency.

Why This is the Ultimate Upgrade

• Optimized Velocity: By removing the corrugated factory tubing, air reaches the throttle body faster, significantly reducing the "dead spot" in throttle response often felt in the early QX56 models.
• Heavy-Duty Filtration: The included high-flow filter is washable and reusable, providing superior surface area compared to the paper OEM panel filters while maintaining excellent filtration in dusty conditions.
• Heat Shield Isolation: The powder-coated heat shield creates a physical barrier against radiant engine heat, ensuring the intake air temperature (IAT) remains as low as possible for consistent power.
