Extreme Turbo Systems Stock Flange Blow Off Valve Pipe Subaru STI 2004-2005
$190.00

If you’re looking to swap out the stock blow-off valve on your 2004-2007 Subaru STI, this replacement pipe is just what you need. It’s designed to let you easily fit a different BOV from another brand, giving you the flexibility to customize your setup. No one wants to be stuck with factory parts when there are so many better options out there, right?

What’s in the Box?

  • Blow Off Valve Flange: This one’s a stock fit, so you don’t have to worry about compatibility issues.
  • Includes AIT Bung + Plug: Makes installation a breeze and keeps everything tidy.

What Fits?

  • Subaru STI 2004-2005

Important Notes:

  • Keep in mind, the BOV itself is sold separately, so make sure to grab one that suits your style.
  • You’ll need an ETS piping kit to get this installed properly, so don’t forget to pick that up too.

This isn’t just any ordinary pipe; it’s built for those who want to take their STI to the next level. It’s a solid upgrade for anyone looking to enhance their turbo sound and performance. Just remember, it’s a direct fit for the 2004-2005 models, so if you’ve got a 2006 or 2007, you might need to look elsewhere. Happy modding!
