mountune Lower Intercooler Pipe Upgrade and Recirculation Valve, Focus ST 2013-18
The original recirculation valve features a rubber diaphragm that does not
function 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 engineers designed a new, more robust valve that
features a metal piston and rubber sealing system
. The new design also features an uprated spring
that improves sealing pressure. This allows the valve to remain closed under
high pressure conditions.
The mountune valve is also serviceable if needed. Also included is our Lower Intercooler Pipe Upgrade featuring a massive 39% increase in airflow. Both items are easily installed and improve turbocharger response and performance.
Mounts directly on turbocharger
Suitable for vehicles running higher than stock boost pressure
Improved response and performance
