Cold Air Intake Kit for Hyundai Sonata (2001-2005) with 2.4L 2.7L Engine

Performance-Focused Air Induction for the 2001-2005 Hyundai Sonata Sirius II & Delta Engines

Who It’s For: Designed specifically for 2001-2005 Hyundai Sonata owners running either the 2.4L Sirius II or the 2.7L Delta V6 engines who want to improve throttle response and hear their engine breathe.

The Problem: The factory intake system on the 2001-2005 Sonata was designed for silence, not flow. Between the restrictive plastic resonators and the prone-to-cracking rubber accordion hoses, the Delta V6 and Sirius II engines often suffer from heat soak and air turbulence. This bottleneck limits the engine’s ability to reach its full volumetric efficiency.

The Solution: We engineered this kit to replace the restrictive factory air box with a high-flow mandrel-bent aluminum pipe. By smoothing the air path and using T-6061 polished aluminum, we reduce intake temperatures and minimize turbulence, allowing your engine to pull in a denser charge of air for better combustion and noticeable gains across the powerband.

Why This is the Ultimate Upgrade

• Enhanced Flow Dynamics: Deletes the factory resonators to provide a straight-through path, resulting in a 5–15 HP increase depending on your current state of tune.
• Heat Dissipation & Durability: Constructed from mandrel-bent aluminum with a polished finish, this kit resists the heat soak issues common with factory plastic units and won’t crack or degrade over time.
• Serviceable Filtration: Includes a high-performance, washable synthetic filter. You won’t need to buy paper filters again; simply clean and re-oil to maintain peak flow.
