IAG 950 CNC Ported Race Cylinder Heads Package for 02-14 WRX, 04-21 STI, 05-09 LGT, 04-13 FXT

This is a real race-oriented EJ head package for builds that need more airflow, stronger valvetrain control, and a better answer for sustained abuse.

• Port work: CNC ported for more airflow than the lower-tier street and competition packages
• Use case: Built for harder drag and track use where rpm, cylinder pressure, and heat are all up
• Power level: A better fit once the combo is clearly in the race-build range

Fitment: 2002-14 WRX, 2004-21 STI, 2005-09 Legacy GT, 2004-13 Forester XT

Why you'd choose it: Choose this when the goal is not just a nice street setup anymore and you need a head package that fits a serious race-minded EJ build.
