These 13-code Denso injectors suit the following 1KD-FTV Euro 4 vehicles:

• Toyota Hilux N70 KUN26 — 1KD-FTV 3.0L (late 2006 – approx. mid-2009, Euro 4, 13-code)

✅ Direct-fit OEM replacement — Genuine Denso 13-code (part numbers 23670-30280 / 23670-39316 / Denso 095000-7780). No modifications required.

Note: 13-code injectors are NOT interchangeable with 11-code or 18-code models. The ECU will only accept injector calibration codes that match its programming. 11-code suits 2005–2006 Euro 3 models. 18-code suits mid-2009–2015 models. If you're unsure which code your Hilux runs, drop your VIN or Rego + State when adding to cart and we'll confirm before dispatch.

Injectors are only part of the job. Here's what else you need for a proper install:

Essential — Genuine Injector & Rocker Cover Fitting Kit:

30-piece genuine kit with all seals, washers and hardware. Never reuse old copper seat washers — they won't seal properly the second time.

Essential — Euro 4 Injector Lines (Rail to Injector):

Reusing old injector lines is the #1 cause of post-install leaks on 1KD engines. These are one-use crush-fit — replace them every time.

While you're in there — upgrade to the Aluminium Rocker Cover:

Factory plastic covers warp and crack over time. Since you're pulling it off anyway, upgrade to alloy once and never deal with rocker cover leaks again.

💡 Pro Tip: Always replace copper seat washers and injector lines when fitting new injectors. Reusing old hardware is the #1 cause of post-install leaks on 1KD engines.

These are standard OEM-spec 13-code injectors for stock vehicles. Running a tune or performance mods? Check out the upgraded 13-code options:

💡 Not sure if 13-code is correct for your Hilux? Drop your VIN (or State + Rego) in the add to cart notes and we'll verify compatibility before we ship. Getting the right injector code is critical — the ECU will reject codes that don't match.

When you provide your rego or VIN we'll confirm the injector type your vehicle left the factory with. However, this may be incorrect if the injectors, harness, or ECU have been previously changed (e.g. a second-hand engine swap or prior incorrect fitment).

⚠️ It's the customer's responsibility to verify injectors before installation. We recommend coding injectors to the ECU while still sealed in their clear bags so the calibration codes are read accurately. The most reliable method is to use a scan tool to read the injector codes currently stored in the ECU.

Q: What does "13 code" mean?

A: The code refers to the first two digits of the injector's calibration number, printed on the injector body. 1KD-FTV engines used three generations — 11-code (2005–2006 Euro 3), 13-code (late 2006–mid 2009 Euro 4), and 18-code (mid 2009–2015 Euro 4). Each code is paired to a specific ECU calibration and they are not interchangeable.

Q: How do I check if my Hilux has 13-code injectors?

A: Unplug the electrical connector on top of any injector and read the first two digits of the calibration code printed on the injector body. If it starts with "13", you have 13-code injectors. Alternatively, use a scan tool to read the injector codes stored in the ECU — this is the most accurate method, especially if the injectors have been replaced before.

Q: Can I fit 13-code injectors to an 11-code or 18-code Hilux?

A: No — the ECU calibration and injector coding are different between generations. The ECU will only accept codes that match its programming. 11-code ECUs reject 13-codes, and 18-code ECUs reject 13-codes. You must use the correct code for your vehicle.

Q: Were there different versions of the 13-code injector?

A: Yes. Early 13-code injectors (23670-30140 / Denso 095000-7030) were prone to cold-start knock and premature wear — these were the most problematic 1KD injectors produced. The later revision (23670-30280 / 23670-39316 / Denso 095000-7780) featured an improved upper spring and DLC-coated armature, significantly reducing cold knock and improving durability. We supply the later improved version.

Q: Do these injectors need ECU coding?

A: Yes — each of the four injectors has a unique calibration code that must be programmed into the ECU using a scan tool. Without correct coding, the engine will run rough, idle poorly, and fuel trims will be off. We recommend coding the injectors before fitting — ideally while still sealed in their clear bags so the codes are read accurately.

Q: Will new 13-code injectors fix rough idle or cold-start diesel knock?

A: In most cases, yes. Worn or early-revision 13-code injectors are a leading cause of cold-start rattle, rough idle, and poor fuel trims on 1KD engines. The later-revision 13-code injectors we supply have the improved spring and DLC coating that specifically addresses the cold knock issue.

Q: How long do 13-code 1KD injectors last?

A: Early-revision 13-code injectors were prone to faster wear, but the later-revision units (which we supply) are significantly more robust. On quality diesel with regular fuel filter changes, expect 150,000–200,000+ km. The biggest threat to injector life is fuel contamination — water or particulate in the fuel system.

Q: Should I replace the injector lines at the same time?

A: Strongly recommended. Injector feed lines are a one-use crush-fit — reusing old lines risks incorrect sealing pressure, leaks, and potential fuel contamination. We stock the Euro 4 Injector Lines Set for this reason (button above).

Q: Do I need a tune with standard 13-code injectors?

A: No tune required for OEM-spec 13-code injectors on a stock vehicle. They're a direct plug-and-play replacement. Tuning is only needed if running upgraded flow profiles (+30 / +50).

Q: Are these new or refurbished?

A: Brand new, Genuine Denso — not reconditioned, not remanufactured, not exchange. No core deposit, no core return. Supplied sealed in genuine Denso packaging.

Q: What are the OEM part numbers for these injectors?

A: Toyota part numbers for the later-revision 13-code include 23670-30280 and 23670-39316. The Denso part number is 095000-7780. The early-revision (23670-30140 / 095000-7030) is no longer recommended — we only supply the improved later version.

Q: Can I upgrade from early 13-code to later 13-code injectors?

A: Yes — if your vehicle currently has early 13-code injectors (095000-7030) that suffer from cold knock, replacing them with the later-revision 13-code (095000-7780) is a direct swap and a worthwhile upgrade. Same ECU coding format, much better cold-start behaviour.
