Extreme Turbo Systems 1.75" Stock Turbo Piping Kit w/ Stock BOV Flange & Process West Street Intake Subaru STI 2015+
$830.00

If you’re looking to boost your Subaru STI's performance, this piping kit is a solid upgrade. It’s designed specifically for the 2015 and newer models and tackles one of the biggest issues with the factory setup: heat soak. The stock intercooler just doesn't cut it when it comes to keeping those intake temps down, especially if you’re pushing your car hard.

This kit relocates your intercooler to the front, where it can actually get some fresh air instead of cooking in the engine bay. What does that mean for you? Well, you can run a larger front-mounted intercooler, which will help keep your air temps lower and improve overall performance. Think of it as giving your engine a nice, cool drink while it works hard.

Now, just a heads up—this is piping only, so you’ll need to grab an intercooler separately. The piping comes in a sleek wrinkle black finish that looks pretty sharp under the hood. Plus, we’ve added an AIT bung with a plug right out of the box, so you can easily install your sensor later on if you choose. Just remember, no sensor is included, so keep that in mind when you’re planning your setup.

Fitment:

  • Subaru STI 2015+

Technical Specs:

  • 1.75" piping diameter
  • Compatible with stock turbo and BOV flange
  • Designed to work seamlessly with Process West Street Intake

So if you’re ready to take your STI to the next level, this piping kit is a great way to start. It’s all about getting that cooler air where it needs to go. Happy modding!
