Subaru STI Air Duct Hose Performance Parts Information serving San Francisco, CA

Enjoy Reliable Performance with an STI Air Duct Hose from Carlsen Subaru Serving San Francisco, CA

Bring more engine performance to your Subaru with our STI air duct hose available in Redwood City, CA

The turbocharged BOXER® engine in your Subaru WRX is great fun, but getting the most from it puts a lot of pressure on key components. One of these components is the air duct hose connecting the intake plenum to the intercooler. Upgrading to this STI high-temperature red silicone hose can handle a lot more pressure and heat for more reliable performance during spirited driving. We recommend this WRX intake system upgrade especially if you have additional power adders.

What are Some Advantages to Installing an STI Air Duct Hose?

While the factory duct hose is fine for normal driving around town and on road trips, if you would like to enjoy a track day or push your WRX to get a bit more from it, then this is an upgrade worth considering. The last thing you want is to lose boost just as you come around a corner before the straight. Since this STI Air Duct Hose can handle the rigors of more spirited driving, you can confidently enjoy the drive, or race, with greater reliability under the hood.
