The Turbo XS Type H blow-off valve adapter kit fits Toyota Supra models with Type H configurations and explicitly supports 1987–1989 Supra applications. It provides the adapters needed to mount a Type H-style BOV on compatible plumbed systems, offering a direct-fit path for owners restoring or modifying the factory valve arrangement for those model years.
