Review: Excellent Parts - Other than the wire being one gauge smaller than the original these work great. Cured my injector code! If you look at the terminals you can see what happens, see how dark the interior is of the one terminal? The other is farther away and you can still see down inside because it is shiny and good. The other picture is of the wiring all covered with heat reflecting tape.
Review: Very good deal - Good quality, great price. Worked like a charm, thanks
