Frequently asked questions

What is the LR105439LR Fuel Injection Kit?
The LR105439LR Fuel Injection Kit is a single-cylinder fuel injector assembly for the 5.0L V8 petrol engine (AJ133). It meters and atomises pressurised fuel directly into the cylinder as part of the engine's direct injection system, covering both naturally aspirated and supercharged applications.
How many LR105439LR injectors are needed for a complete V8?
A complete 5.0L V8 (AJ133) needs eight LR105439LR injector assemblies, one per cylinder, because this kit is supplied per cylinder. Many workshops replace the full set together so all injectors are the same age and flow, though a single failed cylinder can be done on its own.
Which Land Rovers use the LR105439LR injector?
The LR105439LR injector fits the 5.0L V8 petrol (AJ133) Range Rover L322 (2010-2012), Range Rover L405 (2013-2022), Range Rover Sport L320 (2010-2013) and Range Rover Sport L494 (2014-2022). Confirm your engine is the 5.0 V8 AJ133 before ordering.
What are the signs of a failing injector on the 5.0 V8?
A failing injector on the 5.0L V8 AJ133 typically causes a misfire, rough idle, poor fuel economy or a cylinder-specific fault code. A leaking or clogged injector can also cause hard starting. Replacing the affected injector restores correct fuel metering to that cylinder.
