Victor Reinz Cylinder Head Gasket - MX-5 1.6 • 61-52425-00

Replacement Victor Reinz cylinder head gasket for Mazda MX-5 Mk1 / NA and Mk2 / NB 1.6 petrol models listed in the compatibility table.

Victor Reinz 61-52425-00 is a replacement cylinder head gasket for the Mazda 1.6 B-series petrol engine. Fitted between the cylinder head and engine block, the gasket provides the critical seal around the combustion chambers while separating the engine's oil and coolant passages.

This gasket has a published 79.5 mm bore diameter and a nominal published thickness of approximately 1.4 mm. It is specifically intended for the confirmed 1.6 applications listed in the compatibility table and should not be assumed suitable for Mazda 1.8 engines simply because they belong to the wider B-series engine family.
