BMW M20 Cut Ring Head Gasket by Athena-SCE

This M20 Head Gasket is specifically engineered to replace BMW part numbers 11121722734, 11121722735, 11121722737, and 11121722738 for the M20B20, M20B23, M20B25, and M20B27 engines used in a variety of BMW models, including the E12, E21, E28, E30, and E34.

Factory OEM & MLS head gaskets are only engineered to handle a limited amount of cylinder pressures before they start to leak, causing a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure.

Athena-SCE Cut Ring Head Gaskets are uniquely designed to handle increased cylinder pressure caused by power modifications, making them the recommended choice for applications making 16+ psi.

Design: Athena-SCE's gasket body is composed of Motorgasket, a reinforced material developed by Athena's R&D department.

This consists of a steel core covered with two layers of asbestos-free aramid fibre and offers excellent thermal and mechanical resistance without compromising its ability to adapt to mating surfaces.

To ensure maximum sealing under all conditions, a silicone bead is also applied to critical sealing areas, such as oil and coolant passages.
