Short Ram Air Intake For Hyundai Sonata/ Kia Optima (2011-2014) with 2.4L L4 Engine Red

High-Velocity Induction: Performance Intake for the Hyundai & Kia Theta II 2.4L

Who It’s For: Engineered for 2011–2014 Hyundai Sonata and Kia Optima owners running the Theta II powerplant who are tired of the stock sluggishness and delayed throttle response.

The Symptom: The factory intake on the Theta II is designed for silence above all else, which often comes at the cost of efficiency. It utilizes a restrictive, multi-chambered plastic resonator box and accordion-style rubber tubing that creates massive amounts of internal turbulence. This turbulence slows down the air column, causing that noticeable “dead spot” when you step on the gas to merge into fast-moving traffic or pass a slower vehicle on the highway.

The Engineering Fix: This system replaces that restrictive plumbing with a smooth-bore, mandrel-bent T-304 aluminum tube. By eliminating the factory baffles and straightening the airflow path, we maintain higher air velocity and reduce the pumping losses the engine faces during the intake stroke. By relocating the high-flow cone filter to a less obstructed area, we increase the oxygen density entering the combustion chamber, resulting in a sharper throttle snap and a resonant, aggressive induction growl under load.

Why Mechanics Choose This Kit

• Measurable Power Gains: This setup is designed to provide a 7–10% increase in horsepower and a 6–8% bump in torque by optimizing the air-to-fuel ratio and reducing intake resistance on the Theta II.
• Acoustic Feedback: Unlike the muted factory box, this short ram system provides a deep, mechanical roar upon acceleration, giving you better auditory feedback from the engine during spirited driving.
• Thermal Management & Durability: The T-304 aluminum construction is not only lightweight but also dissipates heat faster than heavy OEM plastics, while the washable, reusable cotton-media filter ensures long-term filtration without the need for constant replacements.
