Cold Air Intake Kit for Mazda 3 (2010-2012) with 2.5L 4 Cylinders Engine

Maximize Airflow and Throttle Response for the 2.5L MZR Engine in your 2010-2012 Mazda 3

Who It’s For: Designed specifically for 2nd Gen (BL Chassis) Mazda 3 owners running the 2.5L MZR L5-VE engine who want to bridge the gap between a daily commuter and a spirited driver.

The Problem: The factory intake on the MZR engine is a heavy, baffled plastic assembly designed primarily for noise suppression rather than efficiency. This restrictive design creates air turbulence and allows for significant heat soak, which starves the engine of the cool, dense oxygen it needs to perform at its peak.

The Solution: We engineered this kit to replace the restrictive stock airbox with a mandrel-bent T-6063 aluminum induction tube. By smoothing out the intake path and utilizing a high-flow washable filter, we corrected the factory design flaws of the MZR engine, delivering reliable performance and a much more aggressive engine note under load.

Why This is the Ultimate Upgrade

• Increased Oxygen Velocity: The mandrel-bent aluminum piping maintains a consistent diameter, reducing the air resistance that plagues the stock 2.5L setup, resulting in up to 10% gains in power.
• Heat Dissipation & Durability: Unlike the factory plastic that becomes brittle over time, our T-6063 aerospace-grade aluminum handles high engine bay temperatures while providing a permanent, corrosion-resistant solution.
• True Bolt-On Fitment: This system is designed to utilize existing mounting points, meaning you can complete the swap in about 20 minutes with basic hand tools—no cutting or drilling required.
