BMW B58 Gen 2 – Athena Cut Ring Head Gasket

$285.00

Description

This B58 Gen 2 Head Gasket is specifically engineered to replace part # 11115WAA04.

Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressures before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi.

A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure.

Athena’s gasket is crafted with premium quality reinforced M0115, an asbestos-free material that’s original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2 bar boost.

Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat.

Please be aware that the gasket  should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm.
