Wiseco SC Gasket - BMW S50B30/S52B32 87mm (US)

This is a Wiseco Sport Compact Multi-Layer Steel (MLS) head gasket specifically made for the 1995-1999 BMW M3 with the S50B30 or S52B32 engine. It's designed to handle the intense pressures and temperatures that come with performance applications, especially those using power adders like turbochargers or superchargers. The MLS design is crucial for keeping a solid seal between the aluminum cylinder head and the iron engine block, which experience different expansion rates under heat.

What makes this gasket stand out is its high-pressure steel-laminate construction. It features internal embossments that actually expand with heat, creating an even tighter seal as the engine gets hotter and combustion pressures rise. This updated design helps prevent leaks and maintain consistent compression, even in demanding conditions. It measures 87mm across the bore and has a thickness of .070 inches, with a total of 5 layers for robust sealing.
