The Torque Solution Tial blow‑off valve adapter is a black, vehicle‑specific fitting for 2002–2007 Subaru WRX and 2004–2018 STI models. It provides the correct interface for Tial-style BOVs to mate with the intake plumbing on those Subaru applications, simplifying installation of an aftermarket blow‑off valve where a matched adapter is required.
