ETS Evo X BOV Recirculating Couplers

These couplers connect the Evo X's bypass/blow-off-valve return plumbing back into the intake. I'd use them to replace split, missing or poorly fitting hoses and retain recirculation where the intake and calibration expect it. Select the straight upper coupler, bent lower coupler or both, depending on which part of the matching ETS arrangement needs replacement.
