Turbo XS hybrid blow‑off valve for 2002–2007 Subaru WRX and 2004 STI applications. This hybrid valve replaces the stock BOV to provide controlled bypass of boost pressure and a characteristic venting response for turbocharged Subaru models of the listed years. It fits directly into compatible factory vacuum and boost plumbing as a bolt‑in upgrade for those vehicles.
