COBB SF INTAKE SYSTEM MAZDASPEED3 2007-2013

The COBB SF Intake System for the 2007–2013 MAZDASPEED3 is a high-performance intake upgrade engineered to enhance airflow, improve throttle response, and reduce pre-turbo restrictions—all while maintaining MAF sensor accuracy for safe, reliable tuning.

Built around a custom CFD-designed velocity stack, the SF Intake includes a precision airflow straightener grid to smooth incoming air as it passes over the Mass Air Flow sensor. This helps eliminate turbulence, which can lead to engine management issues, and ensures consistent readings for optimal performance.

The one-piece intake body is made from a high-temperature plastic composite, reducing heat soak and saving weight compared to metal alternatives. It connects to the turbo via 4-ply steel-reinforced silicone couplers, ensuring durability under boost and under-the-hood heat.

Installation is simple and requires no cutting, trimming, or permanent modification. The pre-oiled conical air filter comes ready to go out of the box. All hardware is included, and the entire setup can be installed with basic hand tools in under an hour.

To support this intake system, COBB offers Off The Shelf (OTS) calibrations through the Accessport. These tunes are specifically designed to ensure your MAF sensor and fueling system work safely with the increased airflow of the SF Intake.

Note: All aftermarket intakes for MAZDASPEED models require tuning. COBB Accessport + OTS maps are highly recommended for safe operation.
