Frequently Asked Questions

Do these injectors need coding after install?
Yes. Each injector has an A9 compensation code that must be entered into the ECU, followed by any required idle/pilot learn procedures with a suitable scan tool.
Will these fit a 4JJ1 or earlier D-MAX?
No. These are for 4JJ3 (2020+) applications only. For 4JJ1 variants, contact us with your VIN or existing injector P/N and we’ll point you to the correct part.
Do I get new seals and washers?
We recommend new nozzle washers, O-rings and leak-off seals on installation. 
Can I install these at home?
Professional installation is recommended. You’ll need clean-room style practices, torque specs, and ECU coding capability to avoid leaks, misfire, or incorrect fueling.
