The Mishimoto cold air intake kit for 2008+ Subaru WRX/STi (polished finish) is a vehicle-specific replacement that removes the restrictive factory airbox to improve airflow. The kit uses a mandrel-bent aluminum intake with an air straightener and CNC-machined MAF housing, places a serviceable oiled air filter outside the engine bay with a heat shield, includes all mounting hardware, and is dyno-proven to deliver measurable gains.
