Hybrid Racing Cold Air Intake System (02-06 RSX & 01-05 Civic Si & 01-05 Civic K-Swap)

Maximum Power Gains with Cold, Dense Air

The Hybrid Racing Cold Air Intake is engineered to deliver the highest horsepower gains possible for the 2002-2006 Acura RSX (Base & Type-S) and 2001-2005 Honda Civic Si. This intake is a true 3-inch diameter system, which provides more airflow than restrictive OEM designs and even most aftermarket intakes. By pulling cooler, denser air from outside the engine bay, it dramatically improves throttle response, increases top-end power, and helps your K-Series engine breathe the way it was meant to. Expect solid gains across the powerband, especially in the upper RPM range where the K20 and K24 really come alive. 

All-Silicone Design Means No Heat Soak, No Compromise

Unlike most intakes that use aluminum or steel piping, this system uses glass-reinforced silicone tubing with a true 3-inch internal diameter. That means no heat soak from hot engine bay temps, no heat transfer like metal pipes suffer from, and no weird resonance or vibration. The flexible silicone also helps reduce any stress on the throttle body and intake manifold, especially on lowered cars or high-vibration builds. It’s lightweight, durable, and resistant to oil, fuel, and chemicals. Plus, it just looks clean under the hood.

Big Power with a Built-In Velocity Stack

Every intake comes with a high-performance air filter and a molded-in velocity stack at the end of the tubing. This setup creates a smooth, laminar flow of air into the throttle body, improving air speed and volume without turbulence. The included 6” tall filter is oversized to maximize flow and filtration, and it’s reusable and washable. This intake is built to work seamlessly with stock or modified K-Series setups, including bolt-on cars or full-on K-swaps.

Designed for Easy Fitment on RSX & EP3

This intake is a direct fit for the 02-06 Acura RSX (Base and Type-S) and the 01-05 Civic Si (EP3). It routes the intake pipe through the fender well and positions the filter in the lower bumper area for optimal cold air access. It includes all necessary mounting hardware and brackets to secure the system without any guesswork. You’ll get a clean install, a better sound from the intake, and no CEL issues. If you’re looking for an intake that performs as good as it looks, this is it.
