OE 110449745R — Cylinder Head Gasket for Nissan

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Position depends on the platform. On most Nissan applications the cylinder head gasket sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Aftermarket cylinder head gasket comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Incoming batches pass a dimensional check, a material look-up against the engine & fuel system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

KingMay supplies OEM-grade aftermarket parts built to the 110449745R factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

Stock references leave Guangzhou within 7 working days. If 110449745R needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.
