The engine also gets a high-flow fuel pump and larger fuel injectors. In a nod to the 2004-07 WRX STI, the S209 even gets an intercooler water spray system, operated via steering wheel paddles. (The old STI, for reference, had a button to the left of its steering wheel.)
The giant wing turns to carbon fiber on the STI S209.
