BMW M54B25 | M54B30 | ATHENA Cut Ring Head Gasket 1.50mm

Produced in very high quality stainless steel, cooper rings exceed the sealing capabilities of conventional fire rings & MLS gaskets and optimise engine performances.
Gaskets with Cooper Ring are produced with a reinforced material M0115, which is asbestos-free, original equipment approved and superior quality. These gaskets stand out also because they itilise separate stainless steel rings (AISI 304) that ensure maximum sealing around the cylinder bore, even on engines with NOS and/or turbo applications in which boost exceeds 2 bar. No head and block machining is required. Finally, the application of silicon beading on critical areas helps to improve sealing around all water and oil cooling passages.
