HKS Head Stud Kit Toyota GR Yaris G16E-GTS

Strengthened head stud bolts for GR YARIS' G16E-GTS engine are now available to further enhance the sealing effect of the GROMMET HEAD GASKET, which is already available for G16E-GTS engine with high combustion pressure.

• By using bottomed type stud bolts, the active threads on the block side are longer and the stress is dispersed, allowing for higher axial force to be endured.
• ARP' Custom Age 625 Plus material gives the highest tensile strength, excellent endurance cycle life and corrosion resistance.
