Cold Air Intake for Infiniti G20 (1991-2002) 2.0L Engines

Optimize Airflow for Your SR20DE Powered Infiniti G20

Who It’s For: Designed specifically for Infiniti G20 owners running the high-revving 2.0L SR20DE engine. This is for the enthusiast who wants to hear the engine breathe and feel a crisp improvement in throttle response during daily driving or spirited weekend runs.

The Problem: The stock intake system on the SR20DE is built for noise suppression, not efficiency. It utilizes a restrictive, heat-soaking plastic air box and corrugated rubber tubing that creates internal turbulence. This setup chokes the engine’s intake charge, preventing it from reaching its true volumetric efficiency.

The Solution: We engineered this chrome-finished intake to replace the factory bottleneck with mandrel-bent aluminum piping. By providing a smooth, consistent internal surface and a high-flow washable filter, we allow the SR20DE to draw in air with less resistance, correcting the factory design limitations and delivering a much-needed increase in mid-range torque.

Why This is the Ultimate Upgrade

• Enhanced Induction Efficiency: By smoothing out the intake tract, this kit reduces turbulence, resulting in a documented increase in horsepower and torque by up to 10% across the powerband.
• Aluminum Construction: Unlike cheap plastic or thin-walled steel, our aluminum piping is lightweight and resists corrosion, while the chrome finish adds a show-quality look to your engine bay.
