Cometic MLS head gasket for BMW S14B20/S14B23 applications comes in a .027" nominal thickness with a 93.4mm bore and uses three to five stainless steel layers for increased strength and rebound. Embossed outer layers coated with Viton resist harsh sealing environments and elevated temperatures, while the center shim can be varied to match thickness needs. The multilayer design equalizes clamp load and reduces bore distortion.
