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

Maximize Throttle Response and Airflow for the 2.4L Theta II Hyundai Sonata & Kia Optima

Who It’s For: Designed specifically for 2011-2015 Hyundai Sonata and Kia Optima owners running the 2.4L Theta II engine family who want a more aggressive intake note and better engine efficiency.

The Problem: The factory intake system on the Theta II is designed primarily for sound deadening, using restrictive corrugated plastic hoses and a bulky airbox. This setup creates significant air turbulence and heat soak, which can leave your engine feeling sluggish during spirited driving or under heavy load.

The Solution: We engineered this kit to replace the factory bottlenecks with mandrel-bent aluminum piping and a high-flow filtration system. By smoothing out the intake path, we allow the Theta II to pull in a higher volume of air with less effort, correcting the factory’s restrictive design and improving overall throttle sensitivity.

Why This is the Ultimate Upgrade

• Enhanced Airflow: The polished aluminum piping provides a smooth interior surface that minimizes air resistance compared to the ribbed factory plastic tubes.
• Lifetime Filtration: Includes a high-performance washable air filter, allowing you to clean and reuse it for the life of the vehicle using standard K&N or AEM cleaning kits.
• Direct Bolt-On Fit: No additional parts or permanent modifications are required for installation; this kit utilizes factory mounting points for a clean look under the hood.
