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. 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.
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.
Q: Can I run +30% on a stock turbo?
A: Yes — +30% works on the factory turbo with a tune. +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.
Q: Do they come with calibration codes?
A: Yes — every injector includes its unique calibration code. Code per cylinder and perform pilot learn after install.
Q: Are the injector bodies genuine Denso?
A: Yes — Genuine Denso 13-code body with MCR upgraded performance nozzle. See Modified Injector Disclaimer for full details.
