ARP Head Stud Kit, BMW N20 / N26

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.
