The IAG 550 short block is built with IAG custom spec H-Beam forged connecting rods. These upgraded connecting rods, along with race bearings, can handle the increased engine load from larger turbochargers or higher boost levels—something the OEM STI rods in stock short blocks cannot reliably manage. This feature is just one of the many reasons why an IAG short block makes a superior EJ25 engine for our customers. 💪 | IAG Performance
