Fitment Information
- Subaru WRX STi (2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 019)
Emissions Compliance
-
50 State Legal - This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number: D-660-21 / D-660-48
Specs & Features
- V2 Geometry Update: completely redesigned shape specifically contoured to clear TGV housings, turning a notoriously difficult install into a manageable project.
- Crush-Proof Strength: Built with 6-Ply Steel Reinforced Silicone, ensuring the hose never collapses or sucks shut under peak boost vacuum.
- Smooth Airflow: Replaces the turbulent "accordion" style factory hose with sleek, tapered interior walls for faster air velocity and sharper throttle response.
- Billet Precision: Features machined billet aluminum adapters for the Post-MAF hose and BPV return, plus a plug-and-play PCV adapter for leak-free integration.
- Heat Defense: The thick silicone structure rejects engine bay heat significantly better than stock, keeping intake air temps closer to ambient.
- Direct Replacement: Designed specifically for 2.4" inlet turbochargers on 2008-2021 STI models.
Product Description
Replacing
the turbo inlet on a Subaru STI is legendary for being a knuckle-busting job. The space is tight, and the factory part is a nightmare to maneuver. COBB Tuning listened to the community and completely re-engineered this essential upgrade with the V2 Design. The new shape is specifically tweaked to navigate around the TGV (Tumble Generator Valve) housings, eliminating the wrestling match usually required to get an inlet tube to sit flush.
But fitment is only half the battle. The stock rubber hose is notorious for getting brittle, cracking near the turbo, and even collapsing flat under high-boost vacuum—starving your engine of air right when it needs it most. COBB Tuning solves this with a robust 6-ply steel-reinforced silicone body that maintains its shape under the most extreme pressure.
Furthermore, the V2 update ditches the protruding plastic fittings for flush-mount billet aluminum adapters, smoothing out the airflow path. By removing the factory "accordion" ribs, this inlet creates a smooth, laminar stream of air into the compressor wheel. Whether you are chasing big power or just bulletproofing your daily driver, the COBB V2 Inlet is the reliable foundation your intake system is missing. Upgrade to the component that fits better, flows better, and lasts longer.
