We have AEM intake maps for the 08+ WRX and 08+ STi. Those vehicles also have separate maps for the Cobb SF intake as well as the stock intake. For other year WRX/STi, you must use the stock intake or Cobb SF intake with our maps (no need for separate maps for Cobb SF in this case). If you use an AEM or other intake with these other model years, you will need a custom tune.
