Victor Reinz Cylinder Head Gasket - MX-5 Mk3 NC 2.0 MZR • 61-37685-00

Replacement Victor Reinz cylinder head gasket for Mazda MX-5 Mk3 / NC and Mk3.5 / Mk3.75 NC 2.0 petrol models listed in the compatibility table.

Victor Reinz 61-37685-00 is a multi-layer steel cylinder head gasket designed for the Mazda 2.0 MZR / LF-series petrol engine. Fitted between the cylinder head and engine block, it provides the critical seal around the combustion chambers while keeping the engine's coolant and lubrication passages correctly separated.

This gasket is specifically suitable for the confirmed Mazda MX-5 Mk3 / NC 2.0 applications shown in the compatibility table and uses a multi-layer steel (MLS) construction designed to cope with the high combustion pressures, temperatures and repeated thermal cycling experienced at the cylinder-head joint.

This gasket is intended for the confirmed Mazda MX-5 2.0 MZR / LF-series applications shown in the compatibility table. It should not be assumed suitable for the MX-5 1.8 simply because both engines are fitted to the NC-generation MX-5; the 1.8 uses a different cylinder head gasket.
