💡 Why Upgrade to Subaru STI Stage 2 Camshaft BC0623 EJ257?
Stock cams are fine—until you add:

Then they become the bottleneck.
Stage 2 cams give you:
- Increased airflow through the head
- Stronger mid-range torque
- More top-end horsepower
- Better overall engine efficiency
What you won’t lose:
- Daily drivability (mostly intact)
- Smooth idle (slightly more aggressive, but livable)
