Shop Infiniti Genuine Parts — OEM Catalog for Japan

Infiniti OEM parts for the Japan market: diagrams, part numbers, and exact fitment

This section complements the model list shown above and helps you use 7zap as an online Infiniti original spare parts catalog for Japan. The configurations and part applications in this page are aligned with the Japan market, which matters because equipment packages, lighting and electrical items, emissions-related components, and even body/interior trim can differ between regions.

Use the catalog to navigate from your vehicle’s series and generation to detailed assembly diagrams, then read the OEM part numbers (original numbers) for ordering and compatibility checks. This workflow is especially useful for Japan-market cars operated in mixed conditions: dense urban traffic, frequent short trips, expressway driving, and variable weather from coastal humidity to colder inland seasons.

Series and generations available on this page

The list above contains the Infiniti range for Japan covered by this page. Here, the catalog focuses on the flagship sedan line Q45, including the generation Q45 G50 (1989 - 1997). Open the generation that matches your vehicle to access groups such as engine and cooling, transmission, suspension, brakes, steering, body panels, glazing, interior, and electrical equipment—each with an exploded diagram and a parts list with OEM numbers.

Even within the same model family, Japan-market variations can affect part selection (for example, region-specific harnesses and connectors, lamps and reflectors, sensors, and trim levels). Choosing the correct region and generation first is the fastest way to avoid mismatched parts.

Search by VIN and by part number

Use the identify your INFINITI by VIN to open a catalog filtered to your build. If you maintain multiple brands or need to identify a vehicle with unclear history, the decode any vehicle VIN helps with any car or truck. You can also search directly by OEM part number to verify applicability across engines, trims, and model years in JAPAN.

Decode an Infiniti VIN and open the parts catalog to identify the vehicle and jump to the correct diagrams. If you work with different makes, you can also use the universal VIN decoder on 7zap.

Already have an OEM number? Part-number search is the fastest route when you are replacing a known component or cross-checking compatibility. Enter the original part number to find the corresponding diagram position and verify that the application matches the Japan market selection.

What the Q45 catalog is typically used for

The Infiniti Q45 is often maintained with close attention to correct original components, because many assemblies depend on exact fit and specification. The Q45 G50 (1989 - 1997) diagrams are commonly consulted when selecting suspension and steering items, brake components, cooling and service parts, body hardware and seals, interior fittings, and electrical elements where connector types or regional equipment can matter.

Choose the appropriate generation from the list above, open the relevant diagrams, and use the OEM part numbers to build a clear, region-correct parts request for your Infiniti Japan vehicle.
