FSWERKS Aluminum Diverter ValveSKU: DV25
Wondering where your boost went? Power delivery not as smooth as it used to be? Most likely your engine's diverter valve is to blame.
What is a diverter valve? A diverter valve (DV) is a pathway for boost when it is not being used by your engine. Whenever the throttle body is closed, like during shifts or deceleration, the boost needs an escape route. If the boost cannot escape during these times, it can back up and cause shocks to the turbo. These shocks will stall the turbo, slowing boost production upon re-acceleration (turbo lag). Even worse, these shocks can cause damage to the turbo. The diverter valve's job is to open when the throttle body is closing or closed, and reroute the boost to the low pressure intake side of the turbo, where it can do no harm.
The stock diverter valve uses a rubber diaphragm to open and close this pathway. This type of design is prone to unwanted boost escape, honking noises, and surging during part throttle.

Had some questions about a diverter valve instead of the blow off valves and they were all answered. As the turbo spools this thing sounds great and has an incredible sound you would never expect. 100% recommended!!
