The mountune uprated turbo re-circulating valve is a direct replacement for the OE component.

Machined from solid aluminium with a piston-type design (compared to the OE diaphragm) the more robust design and material are suitable for vehicles in advanced state of tune.

A diaphragm-design recirculation valve could function less effectively when the pressure differential across the turbocharger compressor housing is increased above the original operating conditions. This can cause the valve to open prematurely, leading to possible turbocharger damage due to increased turbo shaft speed.

mountune's engineers have designed an uprated, more robust valve, that features a metal piston and rubber sealing system. This design also features an uprated spring that improves sealing pressure, which allows the valve to remain closed under high pressure conditions.

This product is compatible with mk2 Focus RS, mk2 Focus ST and mk3 Focus ST.

Features:

• Mounts directly on OE turbocharger
• Easy installation
• Suitable for vehicles running increased boost pressure
• Superior piston type design
