COBB Tuning LF Bypass Valve - 2015-2021 Subaru WRX / 2014-2018 Forester

Cobb Engineering for the VA WRX

The Cobb Tuning LF Bypass Valve - 2015-2021 Subaru WRX / 2014-2018 Forester for the 2015-2021 Subaru WRX is a direct-fit upgrade developed by Cobb Tuning as part of their comprehensive platform-specific lineup for the VA WRX. Every Cobb product for this platform is engineered around the factory fitment points and validated on Cobb's own development vehicles — the result is hardware that installs without modification and performs as intended from the first drive.

Platform-Specific Engineering — Not a Universal Fit

Cobb designs every product for the specific platform it covers — not as a universal part adapted to fit. The VA WRX version of this component accounts for the factory geometry, mounting points, and clearances specific to this model year. That means correct fit, correct function, and no compromises from a part designed to fit many cars at once.

Part of the Cobb Ecosystem

This component is part of Cobb's broader product lineup for the VA WRX. Cobb designs their hardware to work together — intake, exhaust, drivetrain, and accessory components are all developed with the same design language and fitment standards, making it straightforward to build a cohesive setup from a single manufacturer.
