This is a complete injector assembly - comprising both the holder and nozzle - for the Land Rover Defender 2.5 naturally aspirated diesel engine. The injector atomises fuel directly into the combustion chamber; a worn or blocked nozzle results in poor atomisation, leading to hard starting, excessive smoke, uneven idle, and increased fuel consumption. Replacing the full holder and nozzle assembly rather than the nozzle alone ensures correct seating, sealing, and spray pattern geometry. Key Features Supplied as a complete unit - injector holder and nozzle included, not a nozzle-only replacement New manufacture, not reconditioned - eliminates concerns associated with worn holder threads or body sealing surfaces Specified for the 2.5 NA diesel engine fitted to the Defender throughout its production run The 2.5 NA diesel uses four injectors - confirm quantity required before ordering; return springs and copper seating washers should be inspected and replaced at the same time Vehicle Fitment Fits Land Rover Defender with the 2.5 Diesel naturally aspirated engine, model years 1986 to 2006.
