Experience worry-free installation as our kit is plug-and-play, eliminating the need for wiring extensions and ensuring compatibility without triggering any check engine lights.

The CTS Turbo Atmospheric BOV Kit, featuring a robust piston design, guarantees longevity, easy installation, full serviceability, an impressive auditory experience, and excellent value. Compact and slightly shorter than the stock unit, our BOV fits seamlessly into the tight confines of the engine bay.
