BMW Evolution Racewerks Blow Off Valve Kits

The Diverter Valve Charge Pipe is available in a mirror polish finish, brushed (or plain) finish, as well as III hard black anodizing for the guys that want the stealthy, factory look. An added benefit of the Type III Hard Black Anodizing is that it hardens the aluminum piping and makes it more durable against accidental damage (like dropping the pipe).

ER also offers the Diverter Valve Charge Pipe in any anodizing color you want and is available in only Type II Anodizing (asthetics). This option is available as a special order item and is not stock.

1/8" NPT Bungs (For Methanol or Nitrous Injectors):

With the popularity of methanol injection and nitrous systems, ER added the option of having either one or two 1/8th" NPT threaded bungs (for methanol or NO2 injectors) that are welded to the diverter valve charge pipe. This allows quick and easy installation of the desired system. Each bung will come with a plug so that you can run with or without the methanol/nitrous injectors. This is perfect for those who do not have the Methanol/Nitrous Injection yet but plan to do so in the future.

104/30/2013335iThe shipping took longer than I expected too but thats not what I am upset about. I had ordered a Synapse BOV w charge pipe for BMW 335i. The parts arrived incomplete, the charge pipe was too short and was missing an addional pipe and cupplers which ran to the intercooler pipe. This is not something that I was expecting considering that I paid $500 for the part. I had opened up the stock charge pipe and diverter valve by the time I realized that the charge pipe that you had sent out was too short. I would like a compensation for this mistake or I will leave a horrible feed back with pictures of the short pipe.
