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

Unleash B18B1 Performance: High-Flow Cold Air Intake for 1994-2001 Acura Integra 1.8L

Who Is This For? Designed specifically for Acura Integra owners running the B18B1 Power Plant (LS, RS, GS, and Special Edition trims) who want to modernize their engine’s breathing, improve throttle response for daily driving, and achieve that iconic high-revving intake growl during spirited canyon runs.

The Factory Restriction: Your 1990s-era factory air box was designed for silence, not speed. Inside that restrictive plastic housing, air is forced through a labyrinth of baffles and a narrow paper filter that chokes the B18B1 engine as the RPMs climb. This results in a "sluggish" feeling when you step on the gas to pass, leaving potential horsepower trapped by poor airflow geometry and heat-soak from the engine bay.

The Engineering Solution: We replaced the bottleneck with a mandrel-bent 2.75" Inch T-6063 Aluminum pipe designed to provide the straightest path possible to the intake manifold. By utilizing a high-velocity, washable, and reusable filter, this kit draws in cooler, denser air from outside the engine bay. This increases oxygen density during the combustion stroke, allowing your ECU to optimize the fuel map for a noticeable bump in mid-range torque and top-end pull.

The Comparative Edge: Why This Beats the Competition

• The Power Gain: Expect a measurable increase in horsepower and a sharper throttle response compared to the laggy feel of the OEM paper filter setup.
• Superior Material Choice: Constructed from T-6063 Grade Aluminum, which offers superior heat dissipation and durability unlike cheaper plastic or thin-walled universal kits that can crack or warp under high engine bay temperatures.
• Serviceable Design: Features a washable and reusable filter. Unlike the factory filter that requires constant replacement, this unit can be cleaned and re-oiled, making it the last intake filter you’ll ever need to buy.
