Make a selection FMCL007PB This turbo recirculation valve is the result of of 25 years of experience and engineering expertise. With the reputation for innovating and manufacturing the best automotive valves in the world, you can be certain that there is currently no better replacement valve available. The fmdv008pa version seen here has the benefit of a 90 degree vacuum port, that can be rotated to three different orientations. This is often the preference where either space is restricted, or the original fitment valve has a 90 degree connection, either on the valve or connecting hose.
