Performance Air Intake For Mazda Protégé (1999-2003) With 1.8L 2.0L MP5 L4 Engine Black

Sharper Throttle Response for the Mazda BJ-Chassis and F-Series Engines

Who It’s For: Designed specifically for 1999-2003 Mazda Protégé and Protégé5 (MP5) owners running the Mazda F-Series engine, including the 1.8L FP-DE and the 2.0L FS-DE powerplants.

The Problem: The factory intake system on the Mazda F-Series is designed for silence and economy, utilizing restrictive plastic baffling and a corrugated rubber snorkel that often cracks with age. This creates turbulent airflow and robs the engine of its ability to breathe, especially during high-RPM spirited driving where these twin-cam engines typically shine.

The Solution: We engineered this performance intake to eliminate the factory bottlenecks. By utilizing smooth-bore T304 aluminum and a high-velocity cone filter, we provide a direct, laminar path for air to reach the throttle body. This corrects the lazy throttle response found in the stock BJ-chassis setup while adding a aggressive, mechanical growl under load.

Why This is the Ultimate Upgrade

• Increased Volumetric Efficiency: Capable of boosting horsepower and torque by up to 10% by reducing pumping losses associated with the stock air box.
• T304 Aluminum Construction: Lightweight, mandrel-bent piping dissipates heat faster than factory plastics and won’t degrade or crack over time.
• High-Flow Washable Media: The included performance filter provides exceptional filtration while allowing significantly more CFM than paper elements. It only requires servicing every 50,000 miles.
