IAG 1150 CNC Ported Drag Cylinder Heads Package for 02-14 WRX, 04-21 STI, 05-09 LGT, 04-13 FXT

This is the deep-end EJ head package for all-out builds. It is meant for combinations where peak airflow, high rpm stability, and drag-focused power take priority over anything street friendly.

• Port work: CNC drag ported for maximum airflow and top-end potential
• Valvetrain: Set up for extreme cylinder pressure and aggressive power levels
• Best fit: Makes sense on serious drag or max-effort race builds, not mild combos

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

Why you'd choose it: Choose this when the rest of the engine is already at the no-compromise level and you want the head package to match.
