It's not just an intake — it's the intake that makes the Cobb tune deliver what Cobb publishes. The SF design uses a sealed airbox to draw from outside the engine bay heat, reducing intake air temperatures versus an open-element design that draws from hot underhood air.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/9b9e1bccc6bb09c796f6757c4a5ec785_fdd88c29-30df-4ae2-81a9-ecd3e57f0f5e.jpg?v=1697910236\" alt=\"COBB Tuning SF Intake Replacement Air Filter - Subaru\/Mazda Models (inc. 2004+ Subaru STI \/ 2007-2013 Mazdaspeed3)\" style=\"width:100%;max-width:100%;margin:20px 0;border-radius:4px;\"\u003e\n\n\u003ch4\u003e\u003cstrong\u003eHeat Is the Enemy of Power — The SF Airbox Knows This\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eOpen-element intakes flow well in a controlled environment, but inside the engine bay of a turbocharged Subaru, they draw in heat-soaked air that the turbocharger and intercooler then have to deal with downstream. The Cobb SF airbox draws from a dedicated cold-air source, keeping intake temperatures closer to ambient. Cooler air is denser air — more oxygen per cubic foot means more fuel can be burned and more power made.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/82be536211eb6dbecfb69c618c4a083e_45f58b99-6eb8-47ca-a2e6-e33cb4a2292d.jpg?v=1697910236\" alt=\"COBB Tuning SF Intake Replacement Air Filter - Subaru\/Mazda Models (inc. 2004+ Subaru STI \/ 2007-2013 Mazdaspeed3)\" style=\"float:right;max-width:47%;margin:0 0 16px 16px;border-radius:4px;\"\u003e\n\n\u003ch4\u003e\u003cstrong\u003eBolt-On Installation, Matched to the Cobb Tune\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Cobb SF SF Intake System installs at the factory airbox location on the Subaru — the factory airbox comes out, the Cobb system goes in its place.

The sealed airbox design is particularly important for daily-driven cars where intake temperatures vary throughout the day — cold air source intake means consistent temps regardless of how hot the engine bay gets.

Based in Austin, Texas, Cobb built their reputation on the Accessport — the most widely used Subaru ECU tuning device on the market — and expanded that into a full ecosystem of intake, exhaust, drivetrain, and engine bay accessories engineered specifically for the platforms they support. Every Cobb product is developed in-house and validated on their own test vehicles before it reaches customers. Subispeed carries the full Cobb catalog because their engineering standards and platform-specific development process consistently produce parts that work exactly as advertised.\u003c\/p\u003e\n\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2004-2013\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eForester\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2002-2014\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eImpreza\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e2015-2021\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWrx Sti\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"COBB","offers":[{"title":"Default Title","offer_id":45712711155798,"sku":"COBB712101","price":19.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0411\/1190\/files\/xn7h8noy5r6o_e9a9b989-257a-4a0b-8863-5b3ef9763fae.jpg?v=1788784253","url":"https:\/\/truegearus.com\/products\/cobb-tuning-sf-intake-replacement-air-filter-subaru-mazda-models-inc-2004-subaru-sti-2007-2013-mazdaspeed3-c9l4d4","provider":"TrueGear","version":"1.0","type":"link"}
