Frequently Asked Questions
Do I need tuning after installing these nozzles?
Yes — a professional ECU remap is required to make full use of the extra fuel delivery and keep EGTs safe.
What injectors are compatible with these nozzles?
They suit Denso 095000-6980 and 095000-8340 injectors found in pre-DPF 4JJ1 engines.
Will these nozzles fit DPF-equipped 4JJ1 engines?
No — these are specifically made for pre-DPF models. Message us if you’re unsure which type you have.
How much power can I expect?
Nozzles alone don’t add power — with tuning and supporting mods (turbo, intercooler, exhaust), they enable significant gains by supplying more fuel.
