How to Read Japanese OE Number Suffixes Without Guessing
Japanese auto parts references may contain a base number, suffix or superseded reference. A suffix should be treated as catalog evidence to verify, not as permission to assume that two references are interchangeable.
Record the complete reference
Copy every letter, number, dash and suffix from the original label or catalog. Keep the complete reference attached to the vehicle model, chassis and production information.
Separate supersession from interchangeability
A catalog may show a replacement reference, but the buyer should confirm whether the newer number replaces the earlier one for the exact application. Do not rely on a similar-looking number or a search result alone.
Wholesale verification fields
- Complete OE number and documented supersession
- Vehicle model, chassis and production range
- Engine, transmission or drivetrain where relevant
- Installation position and supplied quantity
- VIN or original sample when alternatives remain

Review BILUSI site search, browse the relevant parts collection, and send the complete reference through the BILUSI wholesale inquiry form. Confirm final fitment by VIN or the applicable parts catalog.
