Turbosmart Blow Off Valve Return Hose Plug

If you are running any fully atmospheric blow off valve you will need to cap off the compressor bypass valve (or blow-off valve, if you prefer) return line. This plug from Turbosmart is just the part for the job. It's made of billet aluminum; secure with the OEM clamps.

Fits all 2002-2007 Subaru WRX and 2004+ WRX STI.
