A diverter valve kit is essentially a boost-pressure bypass that prevents the boost pressure from being slowed when the throttle closes. With this system, the pressure is diverted directly upstream of the throttle body. As the valve is positioned downstream of the intercooler, only cooled air is recirculated.
On many engines, the standard diverter valve is positioned upstream of the intercooler, meaning that hot, uncooled air is recirculated. This high-performance silicone hose kit from Silicone Factory Hoses is the ideal solution for preventing power losses caused by gradual damage to the standard diverter valve.
The standard diaphragm valve is fitted in a very hot area of the engine bay. Over time, continuous exposure to heat damages the valve, causing it to leak. A leaking valve leads to poorer throttle response and power losses, which are often not noticed immediately because the damage develops gradually rather than occurring suddenly. The driver consequently becomes accustomed to increasingly poorer response and reduced power.
The Silicone Factory Hoses diverter valve hose kit allows the valve to be relocated to a cooler area of the engine bay. This prevents heat-related damage and allows cooler air to be returned to the intake system. The cooler the air, the greater its density; greater density improves cylinder filling and therefore increases power.
This diverter valve hose kit can be used with the standard valve or with another recirculating valve featuring a piston mechanism, which responds considerably better than the standard diaphragm valve.
