Description

IRP Platinum Line pistons are made in Italy from 2618/A billet with a "Double Bridge" design for strength and minimal weight. They feature a galvanic process on the combustion area and first ring land for increased strength and reduced blow-by. DLC (Diamond Like Carbon) thick wall gudgeon pins are included. The IRP Platinum Line Toyota G16E-GTS conrods are machined from 35NCD16 forged steel in an H-beam configuration. They are "deep freeze" treated at -180 degrees Celsius for stress relief and improved wear resistance (2100Mpa, 15% stronger than 300M). Paired with ARP +625 rod bolts.
