The Racer X Fabrication BPV block off for the 1991-1995 Toyota MR2 was designed to eliminate the OEM BPV valve. The block off can assist in maintaining boost pressure between shifts and improve spool response. The block off plate is CNC machined from 6061-T6 aluminum and includes a new o-ring seal to replace the old OEM rubber seal. The BPV block off comes in a raw finish and the Racer X logo is CNC etched into the face of the plate.
