Cold Air Intake Kit for Hyundai Sonata Optima (2011-2015) with 2.4L Engine

Maximize Throttle Response and Airflow for Your Sonata & Optima Theta II GDI

Who It’s For: Designed specifically for 2011–2015 Hyundai Sonata and Kia Optima owners running the 2.4L Theta II GDI engine who want to improve daily drivability and engine efficiency.

The Problem: The Theta II GDI engine is a solid performer, but the factory air intake is plagued by restrictive baffles and accordion-style plastic tubing designed for silence rather than speed. This setup creates turbulence and traps heat, leading to sluggish throttle response and a loss of potential power at higher RPMs.

The Solution: We engineered this kit to replace the restrictive factory airbox with a mandrel-bent, mirror-polished aluminum intake tract. This provides a direct, smooth path for oxygen-rich air to reach the combustion chamber, correcting the airflow limitations of the Theta II GDI while offering better heat dissipation than stock plastic components.

Why This is the Ultimate Upgrade

• Optimized Power Delivery: Eliminates intake turbulence to provide a calculated gain of 5–15 horsepower and a noticeable increase in mid-range torque.
• Advanced Thermal Management: High-grade polished aluminum piping reflects radiant engine bay heat better than stock composite materials, keeping the intake charge cooler.
• Lifetime Filtration: Includes a high-flow, washable, and reusable pleated air filter, eliminating the need for restrictive paper filters and reducing long-term maintenance costs.
