Cold Air Intake for Acura RSX (2002-2006) Base Model 2.0L Vtec Engine

Optimize Airflow and Throttle Response for the Acura RSX K20A3

Who It’s For: Designed specifically for 2002-2006 Acura RSX (Base Model) owners running the K20A3 engine family.

The Problem: The K20A3 engine is a reliable i-VTEC platform, but it is trapped behind a restrictive, heavy factory airbox designed more for silence than performance. This bulky plastic housing creates turbulence and restricts air volume, which often leads to a “mushy” throttle feel and prevents the engine from breathing efficiently during mid-to-high RPM transitions.

The Solution: We engineered this Short Ram Intake to eliminate the factory bottlenecks. By utilizing high-velocity T-304 aluminum piping and a high-flow dry filter, we provide a direct path for air to reach the manifold. This kit corrects the factory design flaws of the K20A3, delivering a sharper throttle response and that signature aggressive intake note that Honda enthusiasts demand.

Why This is the Ultimate Upgrade

• Enhanced Induction Efficiency: By reducing intake restriction, this kit typically provides an 8-10% increase in horsepower and torque, specifically noticeable in the low-to-mid RPM range.
• Superior Build Quality: Constructed from lightweight T-304 aluminum, which offers excellent heat dissipation compared to factory plastic, ensuring a more consistent intake charge temperature.
• Maintenance-Free Filtration: Features a washable and reusable "Dry" air filter. No messy oiling required—simply wash, dry, and reinstall for long-term performance.
