2019 Subaru WRX STi S209, STI engine cover on HKS-upgraded 2.5L turbo flat-four

By William Maley

The matte black STI engine cover dominates the engine bay of the S209, with red intake components and the intercooler visible behind it. This 2.5L turbocharged EJ257 flat-four, upgraded with an HKS high-flow turbocharger, produces 341 horsepower in the 209-unit US homologation special.
