Cometic 01-05 Mazda 1.8L BP DOHC 84mm Bore .030 inch MLS Head Gasket

If you're rebuilding the top end of your 2001-2005 Mazda Miata, a solid head gasket is crucial for keeping everything sealed up tight. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of the 1.8L BP DOHC engine, especially if you're looking to get more performance out of it.

Cometic uses multiple layers of stainless steel for strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that seals well even on slightly imperfect surfaces. This gasket has a compressed thickness of 0.036 inches and is designed for an 84mm bore, which is 0.030 inches undersize from the factory specification. This means it's intended for engines that have been machined or honed to that specific size.

Because it's an MLS gasket, it doesn't require any additional sealants, making installation a bit more straightforward. It's a well-built option for both aluminum and cast iron engine blocks, offering good sealing performance for your Miata's engine.
