Description

The Flyin' Miata head gasket is constructed from all-metal, layered steel, offering a durable replacement for the factory composite item. It is specifically designed for high boost applications and features an 80mm bore, compatible with 1.6 engines that have up to a 2mm overbore. This gasket has a compressed thickness of 0.040", ensuring the engine's compression ratio remains unchanged. This particular gasket is an exclusive offering from Flyin' Miata. This head gasket fits 1990-1993 models. However, it is important to note that this 1.6 head gasket may not be compatible with 1.6 engines installed in MX-5s after 1993. Flyin' Miata has stated they do not have access to European parts or engines to confirm compatibility for those specific vehicles.
