Zerosports Twin Scroll High Performance Turbo A/R25 Subaru WRX STI 02-07

-The Zero/Sports A/R25 Turbo allows for improved torque response through low and mid ranges.
-The Turbo spool is drastically improved by the use of a a ball bearing design and a 70mm compressor wheel that easily supports 400+ horsepower and consistent power throughout the entire RPM range.
