3 essential STI Sport Package mods for the 2015 Subaru WRX [video]

Scott Adkins at Subaru of America service engineering center shows us how he installs the STI Sport Package designed for the 2015 Subaru WRX. These factory parts are available from Subaru and can be added to your 2015 WRX to give it more power and a more engaging driving experience. The Subaru STI Sport Package mods are covered under all factory warrantees.

The 2015 WRX STI Sport Package performance parts were developed jointly by Fuji Heavy Industries, Ltd. (FHI, the maker of Subaru vehicles); Subaru of America, Inc. (SOA); and Subaru Tecnica International (STI). The team members who helped develop the WRX Sport Package are Kunio Kameyama, FHI Accessory Quality Assurance; Yukiji Nakano, SOA Accessories Coordination; Gordon Yeung, SOA Project Engineering – Performance; and Yoshitaka Yamamoto, FHI Performance Accessories Development.

STI cat-back exhaust

The STI exhaust will give the stock 2015 WRX a better exhaust note and give it a little more power. Anytime you can make the new 2.0-liter turbo powerplant breathe better it will improve performance over the stock exhaust system. The STI Performance cat-back exhaust system has practical benefits that allow exhaust gases to flow more freely, so the 2.0-liter turbo Boxer engine “breathes” better, which helps improve overall efficiency. The performance exhaust removes spent gases quickly and easily under all conditions. We aren’t sure how much power increase there is, but it will effectively improve performance. The system comes with the STI logo stamped on the exhaust tips.

6-speed Short Throw shifter

The Short Throw Shifter is a must for performance enthusiasts. This enables the driver to select the right gear much quicker for a more engaging driving experience. The shorter throw enables faster shifts and has a more positive feel than the original-equipment shifter. Anyone who has experienced this on the track can attest that quicker, more precise shifts translate into an overall more engaged driving experience. The shifter gives the WRX a sportier feel on the road or track. It also comes with a custom STI shift knob.

STI 15 Spoke 17-inch Black Wheels

You might not think that wheels can make a different, but they can have a big effect on the handling of your WRX. The unique STI 15-spoke 17" Black Wheels help enhance overall visual appeal and and they also improve handling. They reduce unsprung weight, which helps to improve handling performance and steering precision.

When ordering a 2015 WRX, performance fans can upgrade with the STI Sport Package mods with Unique black wheels, Short throw shifter, STI Shift knob and Cat-back performance exhaust system. They can be added to all 2015 Subaru WRX trim levels equipped with the new 6-speed transmission.
