The Tomei Blow Off Valve is a strengthened valve with turbine protective function that also has the supercharging pressure relief removed.

The blow off valve is not a atmospheric release type but a bypass type. For a 4G63 to be tuned, this item will be missed, it is a must have.

Please note, the 191186 for VII-IX has a metal body. Also has a resistance to boost pressure which exceeds the resin and can correspond with the use of a higher boost.
