This main stud kit includes hardened parallel-ground washers and aerospace quality nuts. Replaces BMW part numbers 11-11-1-713-525 (11111713525) and 11-11-2-244-286 (11112244286).

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.

If there is a large amount of oil on the sides of the engine or if you can smell burning oil, chances are it's a bad valve cover gasket. The gasket fails and allows oil to seep down onto the side of the engine and other parts causing a mess and reducing the amount of oil in your engine. This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes everything needed to re-seal your engine's head.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs, particularly on the S54 3.2 liter engine. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated to 200,000 psi, ensuring complete heat penetration. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best S54 head studs we've found for the E46 M3 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. (Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!)

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.​

These head studs fit the following BMWs/engines
2001-2006 E46 M3 coupe & convertible
2001-2002 MZ3 M Roadster & M Coupe (with S54 engine)
2006-2008 MZ4 Z4 M Roadster & M Coupe
