My Blow Off Valve is Vented So I need to buy one recirculated, Does anyone know the part number for the OEM 1g or 2g blow off valve or where can I buy one that is recirculated back into the air intake or an aftermarket one.
 
Solution
OP: To answer your question:

  • 1g bypass valve: MD160689 (discontinued)
  • 2g bypass valve: MD175728

For this to be helpful, you will want to share what you are currently running. The recommendation will vary based on what your current flange is. Without this, recommending any type of bypass valve is useless.
What BOV do you have? Because if yours can be recirculated then you only need to buy the hose to run it back into the intake.

Since you have the stock 2g piping, you would maintain a very clean OE appearance using the EVO MR bypass valve.

Part # 1545A001

Check classifieds or post a wtb ad.

This is a simple bolt-on with no modification necessary. You will need the recirculation tube (mb906455). They should be quite easy to get used if you aren't looking for a new one.
