Blitz's SUS Intake for the 08-09 WRX & STi features beautiful carbon fiber intake housing which contains a SUS air filter. This intake adds power and style with its unique design. The SUS filtration element features 200 micron mesh and a 150 micron crown; it is exceptionally resistant to wear, and extremely free-flowing. The Blitz SUS Intake filter also straightens airflow through to reduce turbulences for improved airflow and mass air flow sensor compatibility. This is the perfect intake system if you are looking to add style to your engine bay or match your carbon fiber hood! A optional Heat Shield is available which helps keep the intake air even cooler.
