Injen now offers upgraded intercooler cores for your 03-06 Evolution. The core measures 23" x 11 1/2" x 3" and fits directly behind the factory bumper with no modification. This kit free's up just over 20hp when used with basic bolt parts (intake/downpipe/exhaust). The core will support up to 750whp which leaves many different setup options open. The inlet and outlet are both 3" and will work with factory piping or Injen intercooler piping.
