Upgrade the performance of your BMW N20 / N26 engine with our custom-designed Head Stud Kit, brought to you by ARP - the world leader in fastener technology.

This kit is engineered to replace BMW part #'s 11127620958, 11127583138, and 11122212157 and is compatible with BMW N20 and N26 turbocharged inline-four engines found in a range of 3-Series, 4-Series, 5-Series, and X-Series models.

This kit offers increased clamping force and enhanced head gasket sealing, which can prevent head gasket failure. This is particularly crucial for high-performance and high boost engines, as the increased cylinder pressure puts additional stress on the head gasket and bolts.

Please note, it is a MUST to drill and tap the four outer 10mm holes in the engine block to increase their size to 11mm holes. This will ensure that all the engine block holes are uniform in size and can accommodate all 11mm Studs. Additionally, it will help distribute even force across the cylinder head-gasket surface.

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.
