Cold Air Intake for Acura RSX (2002-2006) Type-S ONLY 2.0L Engine

Maximize VTEC Airflow: High-Flow Intake for Acura RSX Type-S K-Series

Who It’s For: Designed specifically for 2002–2006 Acura RSX Type-S owners running the legendary K-Series engine family.

The Problem: The factory airbox on the K-Series is designed to prioritize silence and cabin comfort over raw flow. For a high-compression, high-RPM engine like the K20A2 or K20Z1, the stock plastic resonators and convoluted rubber hoses create significant turbulence. This restriction chokes the engine right when the VTEC crossover occurs, preventing the engine from reaching its full volumetric efficiency.

The Solution: We engineered this short ram intake to correct the factory design flaws of the K-Series induction tract. By utilizing mandrel-bent T-304 aluminum, we provide a smooth, consistent path for air to reach the throttle body. This eliminates the intake vacuum lag found in the stock setup, delivering reliable performance and that signature high-RPM K-series induction roar.

Why This is the Ultimate Upgrade

• Optimized Throttle Response: By shortening the intake path and increasing the diameter, we’ve improved the air velocity, leading to an immediate 8–10% gain in mid-range torque.
• T-304 Aluminum Construction: Unlike cheap plastic intakes that can warp or crack under engine bay heat, our lightweight aluminum piping dissipates heat quickly and maintains structural integrity for the life of the vehicle.
• Direct Chassis Integration: This is a true bolt-on kit. We’ve designed it to utilize factory mounting points on the DC5 chassis, making for a straightforward installation that requires zero permanent modifications.
