Euro Sport Performance Diverter Valve - VW Mk4 /Audi 1.8T/2.7T
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 decelleration, 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.
Our diverter valves has been developed as direct-replacement, alloy body diverter valve with piston and spring design that eliminates all of the above problems.

Great quality part for the fraction of the cost of others. Love the all aluminum design, should last much longer than the stupid plastic one.
