IAG 800 CNC Pocket Ported Competition Cylinder Heads Package for 2015-21 WRX

This is the stronger FA20DIT head package for WRX builds that are clearly past the basic bolt-on level and need better airflow plus better valvetrain control.

• Port work: CNC pocket ported for better flow and stronger high-power capability
• Use case: Good fit for harder-driven WRX builds where the engine combo is already getting serious
• Power level: Built around the 800 package range

Fitment: 2015-21 WRX

Why you'd choose it: Choose this when you are building a real power WRX and want heads that fit the rest of the combo instead of becoming the compromise.
