The Cometic C4122-036 is a multi-layer steel (MLS) cylinder head gasket for the Mazda 1.6L B6 engine (Cometic lists B6D/B6T/B6ZE) with an 80 mm bore opening and a compressed thickness of .036 in. Cometic lists it for the 1990-1993 Mazda Miata (NA, 1.6L B6ZE). Gasket thickness is one of the variables used to set compression ratio and piston-to-head clearance in a built engine.
- 80 mm bore opening, the only bore size Cometic lists for the B6 (the B6's stock bore is 78 mm)
- Compressed thickness .036 in; Cometic does not publish a compression ratio for this gasket, so calculate it for your build
- 3-layer MLS (multi-layer stainless steel) construction
- Outer stainless steel layers carry a .001 in Viton rubber coating; installed dry, without additional sealant (Cometic says extra sealer can hinder sealing)
- Requires smooth, flat and true head and block deck surfaces; Cometic recommends a surface finish of 50 Ra or finer
- Made to order by Cometic; use the head bolt (fastener) manufacturer's torque values
Fitment: 1990-1993 Mazda Miata (NA6, 1.6L B6ZE). Not for the 1994-2005 1.8L BP engine: Cometic sells separate BP gaskets for those cars.
