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

High-Flow DC Sports Air Intake for 2002-2006 Acura RSX Type-S

What it Does: The DC Sports Short Ram Intake System (SKU: SRI6514) replaces the restrictive factory airbox with a high-flowing, mandrel-bent aluminum tract to improve throttle response and induction sound while remaining 50-state C.A.R.B. compliant.

The Stock RSX Airflow Bottleneck

The factory intake system on the DC5 chassis is engineered primarily for noise suppression rather than optimal volumetric efficiency. Acura utilized a series of baffled plastic resonators and a constrained, corrugated rubber intake hose that introduces significant air turbulence. This localized turbulence, combined with the inherently restrictive paper panel filter, stifles the upper RPM breathing capabilities of the high-revving K20 engine. As a result, the K-series engine suffers from muted VTEC crossover acoustics and delayed throttle response during spirited driving conditions.

The Engineering Solution

This DC Sports short ram intake remedies factory restrictions by utilizing a smooth, mandrel-bent aluminum intake pipe that significantly reduces aerodynamic drag within the induction tract. By straightening the airflow path and replacing the dense paper element with a washable, high-flow performance air filter, this system maximizes the volume of ambient air delivered to the throttle body. The aluminum construction ensures rigid durability, while the precision-engineered brackets prevent vibration without requiring core support modifications. Operating under C.A.R.B. EO# D-370-15, it delivers a pronounced, aggressive induction note and sharper throttle transitions while keeping your RSX emissions-compliant in all 50 states.
