Ram Air Intake For Kia Optima/Spectra (2001-2006) with 2.4L/2.5L/2.7L 7L Engines Black

Breathe New Life Into Your Kia Optima and Spectra Sirius II and Delta Engine Families

Who It’s For: This intake system is engineered for owners of the 2001-2006 Kia Optima and Spectra looking to extract more efficiency and a more aggressive tone from the Sirius II (2.4L) and Delta (2.5L/2.7L) engines.

The Problem: From the factory, the Sirius II and Delta engine families are strangled by restrictive, baffled plastic air boxes. These units were designed primarily for engine silence, not performance. They create significant air turbulence and heat soak, which leaves the engine feeling sluggish during off-the-line acceleration and mutes the natural mechanical character of the V6 and inline-four powerplants.

The Solution: We have replaced the cumbersome factory air box with a high-velocity mandrel-bent T304 aluminum intake. By smoothing out the air path and utilizing a high-flow washable filter, this kit reduces intake resistance. This ensures your engine pulls in a larger volume of cooler air, correcting the factory’s flow limitations and providing a crisp, responsive throttle feel that the stock plastic tubing simply cannot match.

Why This is the Ultimate Upgrade

• Performance Induction: By eliminating factory baffles, this system allows for a more direct air path, supporting gains in both horsepower and torque across the RPM sweep.
• T304 Aluminum Construction: Unlike cheap plastic that can warp or crack over time, our lightweight T304 aluminum piping is built to handle engine bay heat while maintaining structural integrity.
• Zero-Mod Installation: This is a true bolt-on kit. You can swap out your factory air box in under 60 minutes using standard hand tools, with no cutting or drilling required.
