IAG 600 Street Cylinder Heads Package for 2015-21 WRX

This is the FA20DIT street head package for a WRX that needs something stronger and more complete than a stock rebuild without getting too wild.

• What you get: Assembled heads built around a strong street and performance use case
• Best fit: Good choice for street cars and responsive turbo setups that still need real reliability
• Power level: Built around the 600 package range

Fitment: 2015-21 WRX

Why you'd choose it: Choose this when you want a clean assembled WRX head package that supports a real performance build but still makes sense on a street-driven car.
