BMW Gaskets, Gasket Sets, Seals, & O-Rings for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

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.

Cometic Head Gaskets are developed with the performance enthusiast in mind. With so many individual requirements for each motor, Cometic offers a number of options to suit your specific motor and needs. *MLS* The Cometic MLS gasket is comprised of three layers of Stainless Steel. Cometic uses Stainless steel for increased strength, it’s ability to rebound and corrosion resistance. The outer layers of the gasket are embossed and coated on both sides with a flouroelastomer rubber based material (Viton) designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The Viton coating is heat resistant to 2500C or 4820F. The center or shim layer of the gasket is comprised of an uncoated Stainless Steel layer, which can be varied to accommodate multiple thickness requirements. The MLS gasket is ideal for both aluminum heads to cast iron blocks and aluminum heads to aluminum blocks. The composition of MLS will also withstand the shearing forces created by aluminum heads on cast iron blocks. No re-torque is necessary. By design, the MLS gasket promotes an even torque load across the sealing surface allowing for measurably reduced bore distortion. *CFM-20* A perforated steel core with an elastomer surface is ideal for head gaskets allowing heat to be drawn evenly across the gasket surface while providing maximum sealing characteristics when exposed to coolants and oils.
