COBB Tuning is proud to announce the release of AccessPORT Stage2 AEM Cold Air Intake Calibrations for 2008, 2009 and 2010 STIs equipped with AEM Cold Air Intake number 21-478WR. Calibrations for 93, 91 and 91 ACN (Arizona, California, Nevada) octane fuels are available. Now you can enjoy the added power of your AEM CAI Stage2 STI with an Off-The-Shelf map developed by COBB Tuning!

These calibrations are intended for Stage2 vehicles with aftermarket downpipe with catalytic converter or full turboback exhaust and AEM Cold Air intake only. Other intakes or catless exhaust systems may cause the vehicle to run poorly. Fueling calibrations may be skewed if other intake systems are used. These calibrations are intended for AEM CAI ONLY; this is not a generic cold air intake calibration.
