Cold Air Intake for Acura Integra LS RS GS GSR SE (1990-1993) 1.8L Engine

Command the Road: Cold Air Intake for Your 1990-1993 Acura Integra B17/ B18 DOHC

Who It’s For: Designed specifically for 1990-1993 Acura Integra GS, RS, LS, and GSR owners running the legendary B17A1 or B18 DOHC engine. If you’re looking to wake up your DA chassis and make it breathe like it should, this is your ticket.

The Problem: Let’s be real, the factory intake on these iconic B-series Integras was a compromise. Honda engineered it for quiet operation and daily comfort, not outright performance. That restrictive airbox and convoluted piping chokes the B17A1 or B18 DOHC, forcing it to pull hot, turbulent air from under the hood. You feel it most when you’re pushing it — that hesitant pull, the flat spots in the RPM range. It’s literally stifling the power potential Honda built into these engines.

The Solution: We engineered this cold air intake system to correct those factory design flaws, delivering reliable, measurable performance. By relocating the filter to an area that draws in cooler, denser ambient air, and utilizing a high-flow, smooth-bore induction tube, your B17A1 or B18 DOHC engine can finally inhale properly. This means more oxygen for a stronger, more complete combustion cycle, translating directly into improved horsepower and torque across the board. It’s not just about the numbers; it’s about how the car feels — more responsive, more eager, more like the Integra you know it can be.

Why This is the Ultimate Upgrade

• Real-World Performance: Experience up to a 10% increase in horsepower and torque. This isn’t just a peak number; it’s a noticeable improvement in throttle response, sharper acceleration, and a stronger pull all the way to redline. You’ll feel the difference, especially in those higher RPMs where the B-series truly comes alive.
• Optimized Thermal Management: Unlike stock systems that pull hot air, our design strategically positions the filter to draw in colder, denser air from outside the engine bay. Colder air equals more oxygen, and more oxygen means a more efficient and powerful combustion — a fundamental principle of engine tuning.
• Enhanced Driving Experience: Beyond the power gains, you’ll immediately notice a more direct connection between your foot and the engine. Gone are the spongy throttle responses; in comes an instant, crisp reaction. Plus, that characteristic B-series induction roar under heavy acceleration? It gets a proper voice, giving your Integra an aggressive, mechanical symphony.
• Durable & Reliable Design: Featuring high-velocity induction piping and a high-flow, reusable air filter, this system is built to last. It maintains steady air velocity for consistent performance, whether you’re commuting daily or taking it to the track. The filtration ensures your high-revving engine is protected from harmful debris while maximizing airflow.
• Hassle-Free Installation: This is a complete bolt-on kit, meaning no cutting or extra fabrication is required. It comes with all the necessary couplers, clamps, and hardware, ensuring a secure fitment directly replacing your restrictive factory components.
