BMW Head Stud Kit 12pt E46 M3/S54 Inline 6

The ARP BMW Head Stud Kit 12pt E46 M3/S54 Inline 6 is designed for high-performance BMW enthusiasts and engine builders who demand reliable cylinder head clamping for the S54 engine. This kit is essential for those pushing their E46 M3 towards higher horsepower through modifications like forced induction or aggressive tuning.

Manufactured from ARP's proprietary alloy steel, these 12-point head studs provide superior tensile strength and consistent clamping force, minimizing the risk of head gasket failure under extreme conditions. The 12-point design allows for precise torque specifications using standard ARP sockets, which helps prevent rounding and slippage that can occur with 6-point alternatives.

Ideal for E46 M3 owners upgrading to supercharger or turbo configurations, this head stud kit ensures that even under high-boost applications, the engine maintains reliability. Each stud is individually quality-tested and comes with ARP fastener lube pre-applied, making it a crucial component for serious builds that require a solid foundation.
