I have a set of extrude honed injectors I got about a year ago from DynoMite Diesel Performance at the tail end of their extrue hone intorductory offer. They have never been a real clean or cool injector (but that is another issue), and I am thinking they may not be from an automotive application. The number on the tip is a 9351- 4 hole with uneven spacing. They are about .060" shorter than the stockers. Does anyone know the original application for this tip?
