BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW 3 Series E93 (2007-2013)

Clear BMW chassis

Please ensure your correct model is selected

Gaskets are key to a properly running and clean engine. They obviously prevent fluid leaks but they're also critical in keeping air either in or out... Air leaks after the air flow meter, also known as vaccum leaks, can induce lean running conditions, fault codes, and poor running conditions. Other seals and gaskets are designed to keep air in. With the sensitivity of OBD systems, leaks will lead to fault codes very quickly which can be tough to diagnose and prevent you from passing state inspections.

We insist on Original BMW or OEM gaskets whenever possible.

Multi-Layer Steel gaskets are comprised of multiple embossed layers of both proprietary high-temperature coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area. The embossed outer layers of our head gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The MLS Gasket (Multi-Layer Steel) features an active combustion seal on multiple layers. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing.
