The ARP 201-4303 head stud kit is custom-designed for the BMW S54 inline 6-cylinder engine and serves as a replacement for the BMW head bolts 11127831862 commonly found in E46 M3 and E36/7 Z3 M Roadster, Z4 M Coupe and Roadster, and E46 M3 CSL.
By installing ARP head studs on an S54 engine, you can enjoy several benefits, including increased clamping force and improved head gasket sealing, which can help prevent head gasket failure. This is especially crucial for high-performance, stroker, supercharged, or turbocharged engines, where increased cylinder pressure can place extra stress on the head gasket and bolts.
The ARP 201-4303 head stud kit is available in two materials: ARP2000 and L19. ARP2000 boasts a tensile strength of 220,000 psi, while L19 has a tensile strength of 260,000 psi.

Please note: After initial assembly, it is necessary to allow the engine to complete a full heat cycle, then re-torque your head studs to spec. This means allowing the engine to warm up to its normal operating temperature, remain at operating temperature for several minutes to ensure each component is uniformly heated, then turned off and cooled completely to ambient temperature.
