K&N 57i Short Ram Intake Kit Subaru WRX / STI 2002-2007

Part #: 57-0626. The K&N 57i Series Induction kit for Subaru WRX and STI cars combines a high - flow K&N air filter and mounting adapter with the factory intake tract.

You can install this kit at the factory intake mounting locations using common hand tools. All necessary hardware is included for a clean and complete installation.
