SF Intake System

The Cobb Tuning SF Intake System is a performance-enhancing upgrade designed to remove pre-turbo restrictions in the stock intake system of the Mazda Mazdaspeed3 (2007-2013 models). This system is CARB certified, making it legal for sale and use on emissions-controlled vehicles in all 50 states. The SF Intake system utilizes several unique features to optimize airflow and performance while minimizing turbulence that can affect engine management. It includes a custom conical cloth air filter, a CFD-designed velocity stack, and an integrated airflow straightener grid. This design ensures smooth airflow past the Mass Air Flow (MAF) sensor, leading to precise readings and preventing potential engine management issues. The intake tube is constructed from a high-temperature plastic composite, which reduces weight and heat transfer. Beyond performance gains, the SF Intake system also enhances the auditory experience of the vehicle. Drivers can expect an increased induction sound, with the turbo spool and bypass valve venting becoming more audible. The filter comes pre-oiled, and the system includes mounting brackets and hardware. It is crucial to note that all aftermarket intakes for MAZDASPEED models require tuning to ensure the MAF sensor reads accurately and the engine operates within safe parameters. Cobb Tuning provides Off-The-Shelf Maps for their Accessport, simplifying the process to install, flash, and go. Users can find the appropriate SF Intake Maps for their vehicle in the MAZDASPEED3 Accessport Map Database.
