Cold Air Intake for Acura Integra GS LS RS (1994-2001) with 1.8L Engine Blue

Optimize Induction Velocity: Cold Air Intake for the B18B1 Powered Acura Integra

Who It’s For: Engineered for 1994-2001 Acura Integra owners running the B18B1 powerplant who are tired of the factory induction lag and want to maximize the efficiency of their non-VTEC setup.

The Symptom: The factory intake on the B18B1 engine is designed for absolute silence and cost-effective mass production, not for performance. It utilizes a heavy, multi-chambered plastic resonator box and an accordion-style rubber intake hose that creates significant internal air turbulence. As the air trips over those ribs, it creates "dirty" airflow that slows down the velocity reaching the throttle body, leaving your GS, LS, or RS feeling sluggish during off-the-line acceleration and mid-range passing.

The Engineering Fix: This system replaces that restrictive plumbing with a mandrel-bent aluminum tube that maintains a constant internal diameter to ensure laminar airflow. By smoothing the path and utilizing a high-flow conical filter, we increase the air density and velocity entering the intake manifold. This allows the engine to reach its volumetric efficiency targets much faster, resulting in a sharper throttle snap and a broad-shouldered power delivery that the third-generation Integra chassis deserves.

Why Mechanics Choose This Kit

• Enhanced Mid-Range Torque: By reducing the vacuum restriction inherent in the stock box, this kit allows the B18B1 to pull air more effortlessly, improving torque response between 3,000 and 5,000 RPM.
• Aggressive Induction Growl: Removing the factory baffles and resonators reveals the raw, mechanical sound of the B-series engine, providing a satisfying roar under wide-open throttle.
• Thermal Efficiency: The blue powder-coated aluminum construction offers a durable finish that resists engine bay heat soak better than aged factory plastics, keeping the intake charge cooler for longer.
