Performance Air Intake for Acura Integra (1994-2001) 1.8L Engine - Red

Your B-Series deserves to breathe. The factory intake on the third-generation Integra was designed for one thing: silence. It strangles your engine with restrictive baffles and a resonator box that kills throttle response. It’s time to ditch the plastic maze and let that 1.8L pull the way Honda intended.

Performance Ram Air Intake System for 1994-2001 Acura Integra RS/LS/GS/SE (B18B1)

If you are driving a DC4 Integra, you know the B18B1 is a legendary workhorse. It may not have the high-RPM scream of the GS-R, but it has a solid mid-range that is often suppressed by the OEM airbox. This T-304 Aluminum Ram Air Intake Kit is the most cost-effective modification to wake up the non-VTEC B-Series engine. By replacing the corrugated rubber intake hose and the restrictive factory filter box with a mandrel-bent aluminum tube, you smooth out the airflow path directly into the throttle body.

The difference isn't just on the dyno sheet, though the 8-10% bump in horsepower and torque is noticeable. The real change is in the pedal feel. The stock system causes a delay in air velocity when you step on the gas. This short-ram design eliminates that lag, providing instant throttle response in the low-to-mid RPM range where you spend most of your time driving. Plus, there is the sound. When you open up the throttle, this intake delivers that deep, throaty induction growl that enthusiasts love, replacing the wheezing sound of the stock unit.

We know that engine bay heat and durability matter. That is why this piping is constructed from lightweight T-304 aluminum rather than cheap plastic that becomes brittle over heat cycles. The kit includes a high-flow, reusable cone filter that eliminates the need to buy disposable paper filters ever again. Whether you have an automatic daily driver or a manual project car, this bolt-on upgrade clears up the engine bay and delivers reliable performance.

Why You Need This Upgrade

• Unrestricted Airflow: Mandrel-bent T-304 aluminum piping removes turbulence caused by factory corrugated rubber hoses.
• Dyno-Proven Power: engineered to deliver an increase of 8-10% in horsepower and torque by optimizing air/fuel delivery.
• Aggressive Acoustics: Deleting the factory resonator box unlocks a deep, sporty induction tone under heavy acceleration.
• Sharper Throttle Response: drastic improvement in low and mid-range RPM pickup, making the car feel lighter on its feet.
• Lifetime Maintenance: Includes a high-quality washable and reusable cone air filter—clean it, re-oil it, and keep driving.
• Direct Fitment: Designed specifically for the B18B1 intake manifold geometry on RS, LS, GS, and SE trims.

Installation Notes

This is a true bolt-on kit requiring only basic hand tools (screwdrivers and socket wrenches). No cutting or modification of the chassis is required. All necessary mounting hardware and couplers are included in the box. Pro Tip: After installation, disconnect your negative battery terminal for 10-15 minutes. This resets the ECU, forcing it to "re-learn" the fuel trims for the increased airflow, ensuring you get the maximum power gains immediately.

Replaces These OEM Applications & Part Numbers

This system is specifically designed for the following vehicles equipped with the 1.8L Non-VTEC engine (Automatic and Manual Transmissions):

• 1994-2001 Acura Integra RS
• 1994-2001 Acura Integra LS
• 1994-2001 Acura Integra GS
• 1994-2001 Acura Integra SE

Note: This kit is NOT compatible with Integra GS-R (B18C1) or Type R (B18C5) models due to intake manifold differences.

Stop driving with a strangled engine. Swap out that aging factory airbox for clean airflow, better fuel economy, and the classic Honda induction sound today.
