Set of 4 × Modified Genuine Denso 11-code injectors upgraded to +30%, +50%, or +100% flow — built for performance early Hilux N70 KUN26 1KD-FTV Euro 3 builds (2005–2006/08, pre-EGR cooler) 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.
Upgraded injectors are only part of the job. Here's what else you need:
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.
🛒 Add Injector & Rocker Cover Fitting KitEssential — Euro 3 Injector Lines (Rail to Injector):
Reusing old injector lines is the #1 cause of post-install leaks on 1KD engines. Always replace when fitting new injectors.
🛒 Add Euro 3 Injector LinesWhile 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.
🛒 Add Aluminium Rocker Cover💡 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.
⚠️ SCV Upgrade: Factory 11-code models run the short-style SCV which is prone to hesitation, stalling, and idle issues. Upgrading to the long-style SCV during injector replacement is strongly recommended.
✅ Genuine Denso 11-code injector body — MCR upgraded nozzles - OEM durable.
Note: 11-code injectors are NOT compatible with 13-code or 18-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.

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: 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: Can I run +30% on the factory HP3 pump?
A: Generally yes, if the pump is healthy. +50% and +100% usually need a higher-output or stroker pump for consistent rail pressure under load.
Q: Why should I upgrade the SCV at the same time?
A: Factory 11-code models run the short-style SCV which is prone to hesitation, stalling, and poor idle. The long-style SCV upgrade eliminates these issues and is strongly recommended when fitting new injectors — especially upgraded flow profiles.
Q: What's the difference between 11-code and 13-code injectors?
A: 11-code injectors are the original Euro 3 G2 Denso design (2005–2006/08) without DLC coating. 13-code injectors (late 2006–mid 2009 Euro 4) have an improved upper spring and DLC-coated armature. They have different ECU calibrations and cannot be swapped.
Q: How are these different from standard 11-code injectors?
A: The injector body is a genuine Denso 11-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.
Q: Will these affect fuel economy?
A: With proper tuning, economy is often unchanged or even improved when towing or under load thanks to more efficient combustion. Without a tune, expect worse economy and excessive smoke.
Q: What supporting mods do I need?
A: For +30%: a quality tune is the minimum, intercooler and exhaust recommended, SCV upgrade strongly recommended. For +50%: upgraded intercooler, 3″ exhaust, boost/EGT monitoring, and SCV upgrade are all strongly recommended. For +100%: full build — big turbo, HP fuel pump, forged internals, quality intercooler, exhaust, SCV upgrade, 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. Buttons above for the fitting kit and Euro 3 injector lines.
Q: Are the injector bodies genuine Denso?
A: Yes — the injector body is a Genuine Denso 11-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.
