Performance Air Intake For Nissan 240SX S13 Silvia (1991-1994) 2.4L L4 Engine Black

Sharpen Throttle Response and Induction Flow for Your S13 KA24DE

Who It’s For: Designed specifically for Nissan 240SX S13 and Silvia owners running the legendary 2.4L KA24DE engine family who want to bridge the gap between street reliability and track-ready air management.

The Problem: The factory airbox on the KA24DE is a massive, restrictive plastic assembly designed more for noise suppression than actual velocity. Over thirty years of heat cycles have likely made your stock rubber accordion hose brittle and prone to vacuum leaks, while the internal baffles create turbulence that kills low-end torque and high-end breathing.

The Solution: We engineered this performance intake to eliminate the bottlenecks in the KA24DE intake tract. By utilizing mandrel-bent T304 aluminum, we provide a smooth, consistent path for oxygen to reach the throttle body, correcting the factory design flaws and allowing your dual-overhead-cam engine to breathe the way it was intended from the factory.

Why This is the Ultimate S13 Upgrade

• Optimized Velocity: The lightweight aluminum piping significantly reduces air turbulence, resulting in a documented boost to horsepower and torque by up to 10% across the power band.
• Enduring Build Quality: Constructed from T304 aluminum, this setup resists the engine bay heat soak that plagues the standard KA24DE, ensuring your intake charge stays as cool as possible.
• Simple Bolt-On Maintenance: Features a high-velocity, washable filter that only requires service every 50,000 miles. It drops right into the S13 chassis using basic hand tools in under an hour.
