DBA 02-10 WRX / 13+ FR-S / 13+ BRZ Premium Front Drilled & Slotted 5000 Series Rotor w/ Gold Hat 2015-subaru-impreza-limited IAG's Stage 4 Cylinder Head

IAG's Stage 4 Cylinder Head Package utilizes a CNC porting program for the V25 heads that was developed over the past five years and tested on the most successful high-horsepower Subarus

To eliminate this problem each head is tapped and threaded plugs are installed

The heads are outfitted with GSC valve train components

Then IAG machines the case halves assembled together in our Haas VF-4SS CNC mill to accept the IAG CLOSED Deck Inserts that transform the block into a solid deck
