Description

 A direct replacement diverter valve will eliminate the notorious "Honking" sound commonly heard when the OEM valves have failed. This valve will restore lost power and will hold more boost pressure than the stock units for added performance. In addition, they recover quicker than the OEM valves which allows better spool up after shifts. The EVOMS billet diverter valves come as a complete kit and carries our exclusive lifetime warranty.

Kevin.  BTW, One of the biggest names in 944 parts has the nerve to sell a generic, nameless version that looks similar to this valve for $195.  I try to get my customers the best prices, not take advantage of them

 Also fits the Porsche Cayenne (955) 957, 958 Turbos.

The 996 TT,  997 TT and 991 TT need 2 diverter valves.  I will combine shipping.

Also fits any of the Audi Turbo engines.  The A3, A4, TT,  S3, S4 and any other  Audi Turbo engine

The shipping price also pays for additional insurance.  This part probably fits a lot more cars than I have listed.  Virtually all German turbocharged cars use the same plastic Bosch diverter valve with 25mm diameter connections.  If you are unsure about the fitment, just remove the diverter valve and measure the 2 connection tubes on the valve.  If they are 25mm in diameter than this will fit.  The engine bays on turbocharged vehicles get so much hotter than naturally aspirated vehicles.  The original Bosch plastic valve will lose it's effective ability very quickly.  This simple, inexpensive upgrade will enable your car to hold a high amount of boost pressure so there is reduced lag while you are shifting gears.  This would actually increase performance even if you had a brand new Bosch plastic valve.
