DESCRIPTION The engine head modifications are necessary to be able to replace the original diesel injectors with the adequate spark plugs 01 Disassemble the original cylinder head 02 Measure the diameter of the original injector seat (D picture 01), in order to chose the type of spark plug (the thread): if the original diameter is mm or less, it is possible to use a spark plug with the thread M10x1; if the diameter is bigger, until to 10,75 mm diameter, it must be used a spark plug with the thread M12x1,25 03 Verify the length L (picture 01), in order to chose the type of spark plug (length of the thread) Consider that when the spark plug is completely screwed in the seat, the only part of it that must enter in the combustion chamber is the electrode, as shown in the picture 02
