Set of 4 × Genuine Denso 18-code injectors upgraded to +30%, +50%, or +100% flow — built for performance Hilux N70 1KD-FTV Euro 4 builds (mid-2009–2015) with tuned ECUs, upgraded turbos, and supporting fuel system mods. Factory injector body with MCR upgraded nozzles - OEM durable. ECU remap required.
⚠️ ECU remap is required for all upgraded injector profiles. Running upgraded injectors without a tune will cause over-fueling, excessive smoke, and unsafe EGTs.
Fitting kit and injector lines sold separately — see below.
We stock everything for a clean Hilux 1KD injector install:
💡 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.
✅ Genuine Denso 18-code injector body — MCR upgraded nozzles - OEM durable.
Note: 18-code injectors are NOT compatible with 11-code or 13-code ECUs. If unsure which code your Hilux runs, drop your VIN or Rego + State in the add to cart notes and we'll confirm before dispatch.
*Orders placed before 2 pm AEST on business days, subject to stock availability.
💡 Not sure if 18-code is correct for your Hilux? Drop your VIN (or State + Rego) in the add to cart notes and we'll verify factory compatibility before we ship.
Where a modified or "+size" injector is advertised or sold as a Genuine injector (of any brand, including but not limited to Denso), it is expressly understood that the term Genuine refers only to the injector body, not the nozzle.
In such cases, the original nozzle has been replaced or modified to achieve the specified increased flow rate, and therefore is no longer the original OEM component. The modification process, performance outcome, and characteristics may vary between manufacturers or suppliers.
Buyers should be aware that while the injector body remains genuine, the nozzle and overall flow characteristics differ from original OEM specifications.
When you provide your rego or VIN we'll confirm the injector type your Hilux left the factory with. However, this may be incorrect if the injectors, harness, or ECU have been previously changed.
⚠️ 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.
Q: Do I need tuning for these injectors?
A: Yes — an ECU remap is essential for all upgraded injector profiles (+30, +50, +100). The tune calibrates fueling, rail pressure, and injection timing to match the increased flow, keeping EGTs within safe limits and maximising performance. Running upgraded injectors without a tune will cause over-fueling, excessive smoke, and potential engine damage.
Q: Which upgrade level is best for a daily/touring Hilux?
A: +30% is the sweet spot for daily driving and towing — it provides noticeable extra torque under load without compromising reliability when tuned correctly. It's the most popular choice for Hilux owners who tow and want a responsive, safe daily driver.
Q: Can I run +30% on a stock turbo?
A: Yes — +30% works on the factory turbo with a tune. You'll notice gains, but to fully benefit a slightly larger turbo and intercooler are recommended. +50% and +100% should have upgraded turbo and supporting mods.
Q: Will these work with the factory HP3 pump?
A: +30% typically works with a healthy stock pump. +50% and +100% usually need a higher-output or stroker pump for consistent rail pressure under load.
Q: Can I run +100% injectors on stock internals?
A: Not recommended. +100% injectors are designed for full-build engines with forged pistons, upgraded fuel pump, big turbo, and supporting mods. On stock internals, the increased cylinder pressures can cause serious engine damage. Stick with +30% or +50% unless your build supports it.
Q: What's the difference between 18-code and 13-code injectors?
A: 18-code injectors are the later Euro 4 G3 Denso design (mid-2009–2015) with DLC-coated internals, faster reaction times, and improved atomisation. 13-code are earlier Euro 4 (late 2006–mid 2009). They have different ECU calibrations and cannot be swapped.
Q: How are these different from standard 18-code injectors?
A: The injector body is a genuine Denso 18-code unit. The original nozzle has been replaced with an MCR upgraded nozzle to deliver increased fuel flow (+30%, +50%, or +100% over standard). They retain factory build quality, ECU compatibility, and calibration codes — but require an ECU remap to run correctly.
Q: Do they come with calibration codes?
A: Yes — every injector includes its unique calibration code, which must be programmed into the ECU during installation. Each code must be assigned to its installed cylinder position using a scan tool. Perform pilot learn after coding for best idle and noise control.
Q: Will upgraded injectors cause more smoke?
A: With a proper tune, smoke is well-managed. Upgraded injectors with correct tuning often produce less smoke under load than a worn standard set, thanks to better atomisation and more complete combustion. Smoke is primarily a tuning issue, not an injector issue.
Q: What supporting mods do I need?
A: Depends on the flow level. For +30%: a quality tune is the minimum, intercooler and exhaust recommended. For +50%: upgraded intercooler, 3″ exhaust, and boost/EGT monitoring are strongly recommended. For +100%: full build — big turbo, HP fuel pump, forged internals, quality intercooler, exhaust, and comprehensive monitoring.
Q: Should I replace injector lines and seat washers?
A: Yes — always replace copper seat washers and injector lines when fitting new injectors. We stock the Genuine Fitting Kit and Genuine Injector Lines.
Q: Are the injector bodies genuine Denso?
A: Yes — the injector body is a brand new Genuine Denso 18-code unit. The nozzle has been replaced with an MCR upgraded performance nozzle to achieve the specified flow increase. See our Modified Injector Disclaimer for full details.
