How to Identify Toyota Hilux Parts by OEM Number

The Toyota Hilux is built in several countries, sold in more than one hundred markets and has run through multiple generations with overlapping engine families. The same model name can therefore cover very different vehicles. For a buyer quoting or ordering parts in volume, the OEM part number is the most reliable identifier available: it removes ambiguity that model names, years and photos cannot.

This guide explains how Toyota part numbers are built, where to find them, and how to use them together with vehicle identification data to avoid mis-supply.

Why model name and year are not enough

A request such as "brake pads, Hilux 2015" can describe at least two generations. The Hilux Vigo (AN10/AN20/AN30 platform) was still in production in some markets in 2015, while the Hilux Revo (AN120/AN130) launched the same year. Within each generation there are further splits:

• Engine family — for example 1KD-FTV or 2KD-FTV diesels on the Vigo versus 1GD-FTV or 2GD-FTV diesels on the Revo, plus 1TR-FE and 2TR-FE petrol engines.
• Drive and ride height — 4x2 low-rider, 4x2 raised ("Prerunner" style) and 4x4 variants can use different brake, suspension and driveline parts.
• Market specification — emissions equipment, cooling capacity, lighting and electrical parts can differ between a Thai-market, Middle East-market or African-market vehicle.
• Mid-cycle changes — facelifts and running production changes can alter parts without a change in model name.

The OEM number captures all of this. Two vehicles that look identical but take different parts will show different numbers in the catalog.

How Toyota part numbers are structured

Toyota part numbers are generally written as ten characters split into two groups of five, for example 90915-XXXXX. The groups carry different information:

Segment	What it indicates	Notes
First 5 digits	The part type or function group	Stable across models; tells you what the part is
Last 5 characters	The specific design variant	Can be numeric or alphanumeric; identifies the exact item

The first five digits are consistent across the Toyota range, which makes them a useful sanity check when reviewing a parts list. Some commonly encountered prefixes:

Prefix	Part type
90915	Spin-on oil filter
04152	Oil filter element (cartridge type)
04465	Front disc brake pad kit
04466	Rear disc brake pad kit
17801	Air filter element
87139	Cabin air filter element
90919	Spark plugs and ignition coils
16100	Water pump assembly

If a line on an order says "oil filter" but the number begins with 04465, something has been copied incorrectly. Catching this before quoting avoids shipping the wrong part in volume.

The suffix is where fitment lives. Two oil filters with the same 90915 prefix but different suffixes are different parts, with different dimensions, thread sizes or bypass valve settings. Never treat numbers that share a prefix as interchangeable.

Where to find the correct number

In order of reliability:

1. The part itself. Genuine Toyota parts and many OE-supplier parts carry the number on the component, its label or its packaging. On a vehicle already in service, the old part is often the fastest reference.
2. An electronic parts catalog searched by VIN or frame number. This is the most accurate way to identify a part for a specific vehicle because it filters by production date and specification.
3. Model code plus production date. Toyota vehicles carry a model code on the identification plate, such as KUN-series codes on KD-engined Hilux Vigo vehicles, GUN-series codes on GD-engined Revo vehicles and TGN-series codes on TR petrol variants. The full model code including suffix letters narrows down body, drive and grade.
4. Workshop records and previous orders. Useful for repeat business, provided the fleet mix has not changed.

Photos and dimensions help confirm a match but should not be the primary identifier, especially for filters, bushings and seals, where small dimensional differences are hard to see.

Supersessions and replaced numbers

Toyota updates part numbers when a design is revised, a supplier changes or several variants are consolidated into one. The old number is then superseded by a new one. In practice:

• A number on a ten-year-old workshop list may no longer be current, but it remains a valid reference because catalogs record the supersession chain.
• A superseded part may be fully interchangeable in both directions, or only one-way (new fits old vehicle, but old does not fit newer vehicle). The catalog note matters.
• Aftermarket manufacturers cross-reference to one or more Toyota numbers. A good cross-reference lists both old and new numbers.

When submitting a list, include the number exactly as you have it. Our team validates each number and flags supersessions before quoting, rather than silently changing it.

Using OEM numbers when buying aftermarket or OES parts

Most wholesale buyers purchase a mix of genuine, OE-supplier and aftermarket parts depending on category and price tier. The OEM number remains the common key across all of them:

• Aftermarket catalogs list the Toyota numbers each product replaces. Search by that number rather than by vehicle description.
• For wear parts with many variants (brake pads, filters, belts), confirm the aftermarket part's reference list includes your exact number, not just "Hilux".
• For dimensional parts (bushings, bearings, seals), ask for key dimensions as a second check.

You can search cross-references on our OEM number lookup. For background on quality tiers, see OEM vs OES vs aftermarket auto parts.

Common identification errors on Hilux orders

Error	Result	Prevention
Ordering by model name and year only	Parts for wrong generation	Include model code or VIN
Ignoring 4x2 vs 4x4	Wrong brake, hub or suspension parts	State drive type and ride height
Assuming petrol and diesel variants share service parts	Wrong filters, belts, plugs vs glow plugs	State engine code
Dropping the suffix or mistyping characters	Unquotable or wrong line	Copy numbers from source, not from memory
Mixing left- and right-hand parts	Wrong lamps, mirrors, arms	Specify LH/RH for every sided part
Assuming a supersession is two-way	Part does not fit older vehicles	Check catalog interchange notes

Also note that left-hand drive and right-hand drive Hilux vehicles use different parts in areas such as steering, pedal assemblies, wipers and some dashboard components.

Building a Hilux parts list for quoting

For each line, the minimum useful set of information is the OEM number, a short description, quantity and the vehicle reference (generation, engine code and drive type). Where you do not have a number, provide the VIN or model code and we will identify it. A full column template is covered in preparing a parts list for a wholesale RFQ.
