The plates that block off the factory valve are only meant to be used with a BOV on a charge pipe. So if you buy a weld on BOV to relocated to your charge pipe. You will need to delete the factory location. That's what those plates are for. If you buy a kit like the cp-e exhale kit. The charge pipe has a relocated bov and a block plate for the factory location.
Agreed with above,
Dont buy or install a block off plate unless you have a BOV located on the charge pipes.
Not allowing the air to vent when you have a turbo causes compressor surge and will damage the impeller bearings, ultimately ruining the turbo.
