P1 Mitsubishi 4G63 Head Stud Kit – 2.0L 6-Bolt, 12pt Nuts, E190 Series, Black Oxide
PN# K089-H01E

The P1 Mitsubishi 4G63 Head Stud Kit (PN# K089-H01E) is engineered to deliver consistent clamping force and superior head gasket sealing for high-performance 2.0L 6-bolt 4G63 engines. Designed as a serious upgrade over factory head bolts, this kit is ideal for boosted street cars, drag racing, circuit use, and high-RPM competition builds.

Each stud is manufactured from P1’s high-strength E190 Series alloy steel, featuring an impressive 190,000 psi ultimate tensile strength. This material provides excellent resistance to stretch and fatigue under extreme cylinder pressures, helping maintain a stable and uniform clamp load to prevent head lift and gasket failure in demanding applications.

A durable black oxide finish enhances corrosion resistance while ensuring smooth, repeatable torque readings during installation. Precision 12-point nuts and hardened washers are included to deliver accurate torque application and even load distribution across the cylinder head.

Built to handle aggressive boost, elevated combustion pressures, and sustained high-RPM operation, this head stud kit delivers the strength, reliability, and consistency that serious 4G63 builds require.
