Short Ram Air Intake for Mazda Miata MX5 (1999-2005) with 1.8L Engine Red

Sharper Throttle Response & Induction Growl for 1999-2005 Mazda Miata MX5 1.8L BP-Series

Who Is This For? Designed specifically for Mazda Miata NB enthusiasts running the BP-Series 1.8L Inline-4 who want to maximize throttle sensitivity for spirited daily driving, autocross, or weekend canyon runs.

The Muzzled Roadster Syndrome: From the factory, your Miata’s 1.8L engine is choked by a restrictive airbox and corrugated rubber bellows designed more for silence than speed. When you heel-toe into a corner and demand immediate power, the engine has to fight through turbulent air and a dense paper filter, resulting in a sluggish mid-range and a muted exhaust note that hides the car’s true personality.

The Engineering Solution: We engineered this Short Ram Intake to provide a high-velocity, direct path for oxygen to reach the intake manifold. By replacing the heat-soaking factory plastic with lightweight aluminum piping and a high-flow open-element red filter, we reduce intake resistance and allow the BP-4W and BP-Z3 engines to breathe freely. This setup restores lost performance in high-mileage vehicles and provides a crisp, metallic induction roar that perfectly complements the MX-5’s lightweight chassis.

The Comparative Edge: Why This Beats the Competition

• The Performance Gain: Delivers a noticeable boost in horsepower and torque (up to 10%), specifically smoothing out the power band unlike restrictive OEM setups.
• Superior Material Choice: Constructed from mandrel-bent lightweight aluminum, which dissipates heat faster and resists corrosion better than cheaper aluminized steel or generic plastic tubes.
• Serviceable Design: Features a high-performance red filter that is fully washable and reusable, saving you money over the life of the vehicle compared to disposable $30 paper filters.
• True Bolt-On Fitment: Engineered to utilize existing engine bay mounting points for an installation that takes less than 60 minutes with basic hand tools—no drilling or custom fabrication required.
