Performance Air Intake For Kia Optima (2011-2015) 2.4L L4 Engine Black

Sharpen Throttle Response and Induction Sound on your Kia Optima Theta II

Who It’s For: Designed specifically for 2011-2015 Kia Optima owners running the 2.4L Theta II GDI engine who want to bridge the gap between daily commuter and spirited sport sedan.

The Problem: The stock intake on the Theta II is designed for silence above all else. With its restrictive plastic baffles and corrugated rubber accordion hoses, the factory setup creates massive air turbulence. This results in a "mushy" throttle feel and prevents the engine from breathing efficiently during high-load scenarios, essentially choking the 2.4L engine of its potential.

The Solution: We replaced the restrictive factory plumbing with a high-flow T304 lightweight aluminum intake track. By smoothing out the air path and utilizing a high-velocity cone filter, we allow the Theta II to pull in a higher volume of oxygen-rich air. This results in a noticeable increase in mid-range torque and a much more aggressive, throaty engine note when you bury the needle.

Why This is the Ultimate Upgrade

• Performance Gains: Experience an increase in horsepower and torque by up to 10% through improved volumetric efficiency.
• Premium Construction: Built with mandrel-bent T304 aluminum piping for maximum durability and heat dissipation compared to cheaper plastic alternatives.
• Zero-Maintenance Filter: Features a high-flow washable cotton media filter that only requires servicing every 50,000 miles under standard driving conditions.
• Direct Bolt-On: Engineered to utilize factory mounting points, making for a straightforward 60-minute installation with basic hand tools.
