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 Custom Age 625+. ARP2000 boasts a tensile strength of 220,000 psi, while 625+ has a tensile strength of 280,000 psi.
