Cobb Air Filter Cleaning Kit - Blue - Universal

Better Air In, Better Power Out — Starting With the Filter

The Cobb High Flow Filter for the Subaru is the simplest airflow upgrade on the car — a direct drop-in replacement for the factory paper filter that flows more air with less restriction while still filtering down to the same particulate level. It's not the most dramatic upgrade on the shelf, but it's the one that takes 15 minutes, costs almost nothing relative to what it enables, and is the correct foundation before any tuning work.

Drop-In Replacement, Immediate Benefit

The Cobb filter drops directly into the factory airbox on the Subaru without modification. No new intake tube, no heat shield delete, no relocation — the airbox stays where it is and the filter slots in. The higher flow rate of the Cobb filter is something the Accessport OTS maps account for, so if you're running a Cobb tune this is the correct filter to pair with it.

The Right First Step Before Going Further

Every Stage 1 Cobb OTS map for the Subaru is calibrated with a high-flow filter in mind. Running the stock paper filter against a tune designed for more airflow leaves power on the table. The Cobb filter is the component that makes Stage 1 tuning work correctly — not just an add-on.

About Cobb Tuning

Cobb Tuning has been developing performance parts and tuning solutions for Subaru vehicles since 1999. 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.
