23670-39365 | Denso Common Rail Injector For 1KD-FTV & 2KD-FTV Diesel Engines

This 23670-39365 common rail injector is a direct-fit replacement for Denso-equipped Toyota diesel platforms, cross-referencing to 295050-0460 and DCRI300460. Built for the 1KD-FTV and 2KD-FTV engine families, it serves workshops and distributors handling Hilux, Fortuner, and Land Cruiser Prado service work where precise fuel delivery under high rail pressure is non-negotiable. The unit arrives as a new assembly, not a remanufactured core, and is suited to diagnostic-driven replacement rather than guesswork parts swapping.

This injector number appears across the Toyota diesel line-up spanning roughly 2005 through 2018 model years, with the most concentrated fitment in Hilux VII (KUN16, KUN26, KUN36), Fortuner diesel variants, and Land Cruiser Prado KDJ150/KDJ155 platforms. Workshops should not rely on model-year alone: Toyota used several injector revisions across the 1KD-FTV production run, and the 23670-39365 sits in the later Denso generation alongside 295050-0460. Always verify the stamped number on the original injector body and the engine code before committing to a four-piece set. Markets with high-mileage Hilux commercial fleets are the primary demand source for this reference.

Common rail injectors are not plug-and-play components. After mechanical installation, each 23670-39365 requires injector code registration via diagnostic equipment-failure to write the new correction codes into the ECU will result in rough idle, excessive pilot injection deviation, and potential DTCs for cylinder balance. Use fresh combustion seals and copper washers every time; reusing old sealing hardware is a leading cause of compression leakage past the injector seat. The fuel rail and lines must be flushed before fitting, as debris from a failed upstream injector can immediately contaminate the new unit's nozzle. Post-installation, run a leak-off test and verify rail pressure holds steady under load before releasing the vehicle.

For independent diesel shops, stocking 23670-39365 addresses a recurring failure point on high-mileage 1KD-FTV engines: worn nozzle spray patterns that cause over-fueling, black smoke, and elevated particulate emissions. The alternative-sending every core out for remanufacturing-introduces turnaround delays that commercial fleet customers will not tolerate. Keeping new assemblies on the shelf lets the workshop complete same-day diagnosis and replacement, capturing labor revenue that would otherwise go to a specialist injector bench. From a distributor perspective, this number moves steadily because the Toyota diesel parc in export markets (Africa, Southeast Asia, South America) continues to run these engines well past 300,000 km, sustaining demand for aftermarket diesel injectors with clear cross-reference documentation.

Every batch of 23670-39365 ships with access to injector flow bench data and factory photographs on request. We encourage buyers to request the current test report matching their order lot-covering back-leak measurement, spray pattern verification, and solenoid resistance check-before finalizing a bulk purchase. Real production floor images are also available for distributors who need to verify assembly environment and component handling standards.

All our diesel spare parts adopt the unified bench test standard. We complete strict bench inspection before shipment and record core performance data on this test form, including pulse width, rotating speed, IMV parameters and tolerance range.
Note: The displayed documents are sample bench test records of diesel pumps, only for reference of our standardized quality control capability.

In addition, original real‑shot photos of packing operations from our own workshop are available. All images are captured on‑site at our factory workstation rather than stock pictures, allowing you to clearly view the full packaging workflow of our fuel injectors, from factory sealing to carton packing.

Q1: Can I mix 23670-39365 with 23670-30400 on the same engine?
A: Do not intermix these numbers within one cylinder head. While they share cross-reference lineage, calibration files and spray characteristics differ by production generation. Fit a matched set of four.

Q2: What causes a brand-new 23670-39365 to fail leak-off testing immediately?
A: Usually contamination, not the injector. Check that the fuel rail was properly flushed and that the return line is unrestricted. Debris trapped in the control valve seat will cause excessive back-leak.

Q3: Do you supply the injector code for ECU programming?
A: The correction code is printed on the injector body label. Photograph the label before installation-once the injector is fitted, the label becomes difficult to read.

Q4: How long can this injector sit on the shelf before installation?
A: Denso-style solenoid injectors have no shelf-life expiration under dry, room-temperature storage. Inspect the nozzle cap for damage and confirm the sealing surfaces are free of corrosion before fitting.

Q5: Is this injector compatible with Euro 4 and later emissions hardware?
A: The 23670-39365 is specified for D-4D applications with DPF systems in several markets. Confirm the vehicle's emissions configuration by VIN before ordering for late-model Hilux or Prado units.

Q6: What core charge applies if I buy in bulk?
A: Core policy varies by order volume and destination. Request the current core return schedule with your quotation-we do not bury core terms in the fine print.
