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

Optimize Airflow and Throttle Response for the 2002-2006 Acura RSX K20A3 Engine

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

The Problem: The factory air box on the K20A3 is a maze of plastic baffles and resonators designed for one thing: silence. Unfortunately, this silence comes at the cost of airflow. The K-Series engine is essentially a massive air pump; when you restrict the intake with a bulky factory housing, you’re choking the VTEC system and leaving horsepower on the table.

The Solution: We engineered this short ram intake to replace the restrictive stock plumbing with lightweight, high-velocity T-304 aluminum. By providing a direct, smooth path to the intake manifold, we correct the factory airflow limitations of the K20A3, allowing the engine to pull in more air with less effort. This results in sharper throttle response and that signature aggressive induction sound when the cams crossover.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Expect an 8-10% increase in horsepower and torque by reducing the vacuum restriction found in the OEM air box.
• Superior Filtration: Features a washable and reusable dry air filter that provides high-flow performance without the mess of oil-recharge kits.
• Built for the DC5 Chassis: Crafted from mandrel-bent T-304 aluminum with a durable black finish, ensuring a perfect fit in the RSX engine bay for both automatic and manual transmissions.

The Performance Promise

Installation Pro-Tip: After installing your new intake, we recommend disconnecting your battery terminal for 30 seconds. This forces the ECU to reset its long-term fuel trims and “learn” the increased air volume provided by the high-flow filter. Buy with confidence knowing this kit includes all necessary mounting accessories for a seamless one-hour install.
