Black Cold Air Intake Kit for Mazda 6 S (2003-2008) with 3.0L V6 Engine

Sharpen Throttle Response and Sound for Your Mazda 6 S Duratec 30 V6

Who It’s For: Designed specifically for 2003-2008 Mazda 6 S owners running the 3.0L Duratec 30 (MZI) V6 engine. Whether you are rowing through gears in a manual or cruising with the automatic, this is for the driver who wants to hear that V6 breathe.

The Problem: The factory air box on the Duratec 30 V6 is a maze of baffled plastic and corrugated rubber designed to prioritize silence over flow. This restriction causes a "lazy" feeling in the mid-range RPMs and hides the aggressive natural acoustics of the 3.0L powerplant. Furthermore, the stock pleated paper filters are a maintenance item that eventually chokes off air as it collects debris.

The Solution: We replaced the restrictive factory plumbing with a mandrel-bent T-304 aluminum intake track. By smoothing out the airflow and utilizing a high-velocity washable cone filter, we corrected the factory design flaws of the Duratec 30, delivering reliable performance and a significantly more aggressive engine note under load.

Why This is the Ultimate Upgrade

• Enhanced Flow Dynamics: By removing the baffled factory resonators, this kit allows the engine to draw air more efficiently, resulting in a dyno-estimated gain of 7-10% Horsepower and 6-8% Torque.
• Premium T-304 Construction: The intake pipe is constructed from lightweight T-304 aluminum with a durable black finish, designed to resist corrosion and look sharp in the engine bay.
• Washable High-Flow Filter: Say goodbye to disposable paper filters. The included high-quality cone filter is fully washable and reusable, providing better filtration and superior airflow.
