Aluminum Turbo Blow Off Valve, Piston BOV — Atmospheric Valve for the Astra VXR 2.0 J type. This piston-design bypass valve is a robust direct replacement for the original diaphragm unit, delivering enhanced longevity and reliable boost relief when you push higher power levels.

Crafted from high‑quality aluminum and finished in a sleek silver, this BOV provides durable performance under boosted conditions. Its piston design stands up to higher boost more consistently than OEM diaphragm valves, and it can be tuned for modified engines by fitting different springs. For installation ease, the top or vacuum connection is angled, helping you fit the valve in tighter engine bays without hassle.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
