Built tough, built right.
Injectors are matched to the engine, not the badge on the tailgate. The same ute can run two or three different injectors across its build life, and the wrong one will not code to the ECU. Pick your make, find your build, and you land on the injectors that actually suit it.

If you already know your code, go straight to your make. If you do not, the section below walks through the four things that decide the part. Most owners do not know their code, and it takes about two minutes to find.
Four things decide the injector: the model, the build date, the engine, and on some vehicles whether it left the factory with a DPF. Get any one of them wrong and the part will not suit.
The compliance or build plate sits under the bonnet or on the driver’s door jamb and carries the month and year the vehicle was built. Build date beats model year every time, because manufacturers change parts mid-year. A Hilux N70 sold as a 2009 can take either the early or the late injector depending on which side of the change it was built.
A lot of Toyota injectors carry a code on the injector body, and that code is what the replacement is ordered by. On the Hilux N70 and the 3.0L Prado they are listed here as Code 11, Code 13 and Code 18. A clear photo of the top of one injector usually settles it on its own.
On the Isuzu D-Max, the Holden Colorado and the 200 Series LandCruiser the injector changed when the diesel particulate filter arrived. Look for the filter in the exhaust ahead of the muffler, or think back to whether the dash has ever run a regeneration message.
Send your rego or VIN and we will confirm the exact injector against the build before you buy. Injectors are coded to the engine and cannot go back once they have been fitted, so it is worth the five minutes. Email sales@willysworkshop.com.au, call (07) 3377 3421 in Brisbane or (07) 5619 7869 on the Sunshine Coast, or use the injector testing and cleaning service if you want them checked before you replace anything.
Three injectors cover the N70 and they are not interchangeable. Code 11 and Code 13 suit the earlier build, Code 18 the later one. The code is stamped on the injector body, so check that before you order rather than going off the year.
The 120 Series Prado shares its injector family with the early Hilux N70 and is listed here as Code 13.
The 150 Series moved to the later injector, listed as Code 18.
This suits the pre-DPF 200 Series. Eight injectors to a set on the V8.
The 70 Series V8 takes the same eight-injector set as the pre-DPF 200.
Six injectors to a set on the straight six.
Two injectors cover this range and build date is what separates them. One suits the D40, D22 and Pathfinder R51 across 2002 to 2014, the other is the 2010 to 2014 D40 and R51. If the vehicle sits near the changeover, send the build plate.
The Ranger and the Mazda BT-50 shared a platform for years, so most of these injectors suit both. Engine size is the first thing to pin down, then whether the vehicle has a DPF.
The 2.5L and the 3.0L take different injectors. Check the engine before the year.
Two engines again, the 3.2L five cylinder and the 2.2L four.
Once the DPF arrived the 3.2L moved to a different injector. This is the one for PX2 and PX3 Rangers and for the Everest.
BT-50 injectors follow the Ranger for the UN, UP and UR, then follow the Isuzu D-Max once the TF arrived in 2020.
Same parts as the PJ and PK Ranger. Pick by engine size.
Same parts as the PX Ranger, and the DPF-type 3.2L injector once that came in.
The TF runs the Isuzu 4JJ3, so it takes the D-Max injector.
The 4JJ1 ran for a long time and was fitted with more than one injector. Whether the vehicle has a DPF is the split that matters most, and the earlier D-Max, Colorado and Rodeo share the same part.
Two versions were fitted before October 2013 and they are listed separately as first and second generation. If you cannot tell which is in the vehicle, send the rego and we will check it against the build.
The RC shares the Isuzu 4JJ1 injector with the D-Max of the same era.
Cummins injectors are chosen twice over: first by year range and pump type, then by what you want the engine to do. A stock replacement, a reman set and a staged performance set can all fit the same engine. Work out the year range first, then tell us the power goal and what the truck tows.
High output and standard output take different injectors. The build plate or the VIN tells us which one you have.
Mechanically it is a workshop job on most common-rail engines, and on many vehicles the new injectors have to be coded to the ECU before the engine will run properly. If you are supplying to your own mechanic, make sure they have the scan tool to write the codes.
On a high-kilometre engine it is usually better to do the set so they are balanced. One failed injector on an otherwise tired set tends to be followed by the next one. We will give you a straight answer based on your symptoms and the kilometres.
New gives the longest service life and is the pick for a hard-worked or high-kilometre engine. Quality reman injectors are tested to specification and make sense on plenty of builds. Both are available across most of the range above.
Injectors are coded to the engine and cannot come back once they have been fitted, which is exactly why we ask for a rego or VIN before anything ships. Send it through and we confirm the part manually.
