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

Optimize Airflow and Low-End Torque for Your Infiniti QX56 VK56DE V8

Who It’s For: Designed specifically for 2004-2010 Infiniti QX56 owners running the VK56DE engine who want to improve throttle response and towing efficiency.

The Problem: The VK56DE V8 is a workhorse, but the factory airbox is heavily baffled and restricted to prioritize cabin silence. This design creates significant air turbulence and heat soak, which can make a heavy SUV like the QX56 feel sluggish during initial acceleration or while pulling a trailer.

The Solution: We engineered this high-performance intake kit to replace the restrictive plastic factory plumbing with a high-flow system and dedicated heat shield. By providing a more direct path for oxygen-dense air to reach the VK56DE, we improve combustion efficiency and deliver the throatier engine note that this 5.6L V8 deserves.

Why This is the Ultimate Upgrade

• Enhanced Volumetric Efficiency: By increasing the volume of air available during the combustion cycle, this kit helps the engine produce more power with less effort, particularly noticeable in the mid-range.
• Integrated Heat Management: The included heat shield helps isolate the air filter from radiant engine bay heat, ensuring cooler intake temperatures for more consistent performance.
• Maintenance & Longevity: Featuring a washable and reusable high-flow filter, you’ll never have to purchase a disposable paper filter again. Simple bolt-on installation requires no permanent modifications.
