Cold Air Intake for Honda Civic MT DX LX EX HX (2001-2005) 1.7L Manual Transmission Only

Wake Up Your 2001-2005 Honda Civic D17 with a True Cold Air Intake Upgrade

Who It’s For: Designed specifically for 7th Gen Honda Civic owners running the D17 series engine equipped with a manual transmission. Whether you’re daily driving an EM2 coupe or an ES1 sedan, this is for the enthusiast looking to improve throttle response and engine acoustics.

The Problem: From the factory, the D17 engine is choked by a restrictive air box and a series of plastic resonators designed more for sound suppression than performance. This setup creates turbulence and pulls in heat-soaked air from the top of the engine bay, which significantly hampers the efficiency of the D17 engine.

The Solution: We engineered this intake system to bypass those factory bottlenecks. By utilizing mandrel-bent aluminum piping and a high-flow micro cotton gauze filter, we provide a direct, cool air path to the throttle body. This lowers intake air temperatures (IATs), allowing for more aggressive timing and better combustion.

Why This is the Ultimate Upgrade

• Proven Power Gains: Dyno-estimated increases of 5 to 10 horsepower and 6 to 8 lb-ft of torque by optimizing air-to-fuel ratios and volumetric efficiency.
• Maintenance-Free Filtration: Features a dry-media micro cotton gauze filter that is completely washable and reusable. Unlike traditional performance filters, this requires no oiling, protecting your Mass Air Flow (MAF) sensor from contamination.
• Manual Transmission Optimized: Specifically clearanced for the shift linkages and slave cylinder placement found on manual transmission models, ensuring zero interference during hard shifts.

The Performance Promise

Lived Experience Tip: To get the most out of this install, we highly recommend disconnecting your battery terminal for at least 10 minutes after the installation is complete. This forces the ECU to reset its long-term fuel trims and “learn” the increased air volume immediately, ensuring you feel the performance difference on your very first drive. Buy with confidence.
