Product Overview
Hard starting, rough running, smoke, diesel knock or poor cylinder balance can be caused by a worn injection nozzle, although compression, pump timing and fuel quality should be checked before parts are replaced.
This replacement nozzle restores the controlled spray pattern at the combustion chamber. It is suited to an injector-service job where the original nozzle is worn, leaking or no longer atomizing fuel correctly.
