K&N 57A-6044 Performance Induction Kit for a range of 2007 - 2009 Subaru Impreza WRX and H4 makes and models
The custom design of the 57A-6044 is made using K&N’s Apollo air filter enclosure along with a K&N air filter. The Apollo’s protective shell provides the benefits of an open cone filter and standard air box in one unit.
The K&N performance air intake system comes with adaptors to fit the Subaru Impreza. By using a CNC mass air sensor pad, K&N keeps your Subaru running within the factory settings. The 57A-6044 also provides excellent filtration and additional power to the engine.
The removable cold air feed attachment on the Apollo allows outside air to enter the unit. Zip ties are also provided to secure the hose in position. It takes about 90 minutes or less to install this kit using simple hand tools. The 57A-6044 also comes with the famous K&N Million Mile Limited Warranty.
