At throtl, we're the ultimate destination for Subaru performance parts.
We have all the compatible upgrades to get the most out of your 2015-2020 Subaru WRX STi. THE WRX STi is similar to the Subaru WRX, but comes with a few additional upgrades, like an EJ25 engine that nets you 300 horsepower. The WRX STi has great horsepower right out of the factory, but for owners looking to get more out of their engine performance you can get simple, bolt-on options. Like the WRX model, the WRI STi is a popular JDM tuner car.
The Subaru WRX STi is modified in similar ways to the WRX. Your Subaru WRX STi exhaust, air intake, and wheels are all popular options for performance upgrades. You can find a huge selection of Subaru WRX STi performance parts at throtl, with popular brands. You can show 2018 Subaru WRX STi brake pads, discs, and rotors with StopTech, or upgrade your 2020 XTi's exhaust with Mishimoto. For more popular brands you love, shop now.
