Mazdaspeed3 SF Intake System Mazdaspeed3 2007-2013 Stealth Black

COBB Tuning SF Intake systems remove a pre-turbo restriction in the stock intake system. They provide great power gains when combined with custom mapping on your Accessport tuner. To maintain optimal air flow, SF Intake systems utilize several unique features such as a custom conical cloth air-filter element and a computational fluid dynamics (CFD)-designed velocity stack. Tuned or stock, with the addition of a SF Intake system turbocharger induction noise and bypass valve venting sounds are much more audible. COBB Tuning SF Intakes were designed to be easy to install without having to modify your car. Installation requires no cutting or trimming of any components and can be completed with simple hand tools. Simply remove the stock air box and bolt the SF intake into place in just minutes. Additional attributes of COBB Tuning SF Intake systems (varies by model): * Temperature-resistant composite construction; saving weight and reducing heat transfer * Integrated velocity stack * Integrated airflow straighteners * 4-ply steel-reinforced silicone post-MAF tubing (where applicable) * Pre-oiled, cleanable, reusable, custom filter element * Air boxes are available for most applications (sold separately) * COBB Tuning off-the-shelf (OTS) maps for the Accessport make SF Intake installs easy: bolt it in, flash, and go IMPORTANT NOTE: Some SF Intakes REQUIRE tuning to ensure the MAF sensor reads properly and the engine operates within safe parameters. Check your application carefully.
