Your factory intake system is built for mass-market silence, utilizing a restrictive plastic resonator box and corrugated tubing. This setup creates chaotic air turbulence that slows down oxygen velocity, resulting in sluggish throttle response and restricted power.
Our Kia cold air intakes solve this by replacing heat-soaking plastics with a smooth, mandrel-bent T304 aluminum intake tube. By maintaining a constant internal diameter, this design converts turbulent air into a high-velocity laminar flow. Relocating the high-flow washable cotton filter allows your engine to draw in a higher volume of dense, cold air with less parasitic drag.
Every bolt-on Kia intake system is designed for a straightforward, 30-to-60-minute installation using basic hand tools. To maximize your engine's total output, pair your specific Kia Optima cold air intake (or Soul, Forte, and K5 model) with our plug-and-play Performance Chips, or upgrade your exhaust flow with our Exhaust Systems.
