Review on 4 Pack Ignition Coil Connector Plug Harness Pigtail Replacement for VW, Volkswagen Audi 1.8T, 2.0T, 2.5L, 3.2L, 4.2L Vehicles by Brent Saake

Well first of all how they compare to OE spark plugs, terrible. You have the wrong wire gauge, too small for 3 large wires and too big for 1 small wire. The supplied crimps are made of aluminum and have low conductivity. I wanted to solder them but my car's existing wiring didn't take the solder I had well enough so I took the easy route and now my car won't start. These connectors also don't have properly adjusted pins, meaning they move about 1-2mm at a time, which probably isn't a big deal but is worth noting. To be honest I just wanted to quickly fix the coil caps until I could afford a replacement wiring harness, but I had to get a wiring harness first because now I drive my fiancé's car to work in the morning.
