These Genuine Denso +30 Upgraded Nozzles can improve Torque and Power and reduce smoke in your 4JJ1* - by reducing the required injector pulse width and allowing a greater amount of fuel to be injected in the correct time frame to produce an optimal burn and optimal mechanical leverage of the piston on the power stroke.
Installation requires specific tools and skills, and it is recommended to be carried out by a Qualified Diesel Repair Shop.
However, installation is generally not an extremely complex job and may be carried out at home.
Note*:
Injectors recommended to be bench tested + shimmed to suit.
ECU Tuning required 🤠
