Customer Review: (see review/s)
  • K&N reports a 12hp gain on a Subaru 2.0 WRX. On my 2.5 2006 model the overall gain in horsepower is slight however throttle response is much better and low end torque feels better. Intake is a bit louder than stock but not distractingly so. Instructions are well written and illustrated and installation was a breeze.
