🔧 Fitment Notes
These suit DPF-model 4JJ1 engines from the late-2016 (MY17) DPF update through 2020 only. 2012–2016 D-MAXs run a different injector — if your existing codes don't start with 9F, stop and message us. Unsure? Send your VIN or the code off an injector and we'll confirm fitment before you order.
🛠 Installation Notes
- Program each injector's 9F compensation code into the ECU — non-negotiable
- Fit new seat washers and torque to spec (washers not included — add a washer kit)
- Keep injector bores clean and carbon-free before fitting
