High-Flow Cast Aluminum Mazda 3 Intake Manifold
Performance Upgrade For Mazda 3 MZR
Ditch the Plastic, Unlock the Power: The Ultimate Mazda 3 Airflow Solution. The factory Mazda 3 intake manifold is a known bottleneck. Constructed from plastic, the OEM unit is prone to heat soak and can even fail or crack under high-boost or high-heat conditions. The JDMPro High-Flow Intake Manifold is the definitive solution for tuners looking to maximize the potential of the 2.0L and 2.3L MZR (and Ford Duratec) engines.

Engineered from high-grade cast aluminum, this manifold offers a massive 20% increase in airflow over the stock assembly. A performance powerhouse, capable of delivering up to a 10% increase in horsepower by optimizing air velocity and distribution to every cylinder.
Whether you are running a naturally aspirated track build or a high-boost turbo setup, the JDMPro Mazda 3 manifold provides the structural integrity and thermal stability needed to keep your engine breathing deep and running efficiently under pressure.
WHAT YOU GET HERE:
- Significant Power Gains: Optimized runner design allows for up to 10% more horsepower and significantly improved mid-to-high RPM torque.
-
High-Velocity Airflow: Delivers 20% more air volume than the factory plastic manifold, reducing intake restriction for faster throttle response.
-
Superior Thermal Management: The cast aluminum construction dissipates heat faster than plastic, stabilizing intake air temperatures and preventing power loss due to heat soak.
-
Built For Boost: Unlike plastic OEM units that can burst under pressure, this manifold is a “must-have” for mild to wild turbo setups.
-
Direct-Fit Design: Engineered as a “bolt-on” upgrade compatible with factory sensors and the OEM throttle body (64mm opening).
FITMENT:
This Mazda 3 intake manifold is a direct replacement for the L-Series/MZR engines found in:
- Mazda 3 (BK/BL) 2.0L MZR: 2004–2013.
-
Mazda 3 (BK/BL) 2.3L MZR (Non-Turbo): 2004–2013.
-
Ford Focus (Duratec): 2.0L & 2.3L models (2003–2011).
*Professional ECU tuning is highly recommended after installation to recalibrate fueling for the increased air volume.
*For optimal results, professional installation is highly recommended.

Delivery arrived on time. So far, my 2.3L MZR drives sharper and glides better on the track.

Great performance boost for my L3VE. Arrived 2 days from the expected ETA, but all good with the packaging. My Mazda now drives more briskly than ever. Good value for money.
