You might find them a little cheaper but probably not by much. Surprisingly dealer prices are often competitive - don't know why that is. There are two basic types of injectors - the old style and the new style. Only the old style, which tend to run about $25 to $30 each can be replaced on a preventive maintenance basis. The new style, i.e. $150 to $250 each, you don't replace just because they've got some miles on them. You clean and refurbish instead. The good news is that the expensive ones rarely go bad.
