For a diesel engine to function correctly, the injector has to produce atomised fuel at a set pressure and a specific time in the power cycle. To achieve this, the injector nozzle might need to be replaced at some stage if the engine is not performing as economically as it used to or if nozzle replacement is an intrinsic part of a car’s service plan.
If nozzle replacement is required, like-for-like is a must, otherwise an injector fitted with the wrong spray angle nozzle may cause engine malfunction.
Our Stock

Our stock of nozzles covers Bosch, Delphi (CAV), Lucas, Simms, Friedman Maier, Zexel (Dieselkiki), Denso (Nippon Denso), Siemans, and many other manufacturers.
Pre-common rail, the style of nozzle might be pintle, pintux, needle valve, longstem, and P-type.
Genuine and good quality replacements are always in stock of this type of nozzle (as well as the common rail type).
In between pre-common rail and common rail, there was the two-stage style of nozzle, and again these are a stock item.
With common rail, there are a multitude of variants of nozzle. Please browse our website or call us to find the most appropriate nozzle for your application.
Fitting the wrong type of nozzle can have quite serious consequences for the performance of an engine.
