Here is the information we have from AWE:
To add to our growing line of BMW Performance products, we’re announcing the release of the AWE Tuning 2007-09 135/335/535 N54 Blow Off Valve / Diverter Valve Kit.
Designed as a cost effective drop in replacement for the failure prone factory diverter valves. This kit features maintenance free diaphragm style valves which have been tested and proven reliable to 750+ horsepower.
In addition, we give clients the option to choose between a Blow Off or Diverter Valve configuration with the same kit. For those wanting to run in Blow Off Valve mode, we include filters to prevent debris from entering the intake tract.
Our valves feature an OE style connection for quick and easy install into the factory charge pipe.
For the 135 we include a few extra components to remove the factory sound baffle. This is necessary for installation.
Warranty is 1 year against manufacturer defect.
