Review on Auto Meter 6171 Cobalt Wideband by Sam Lee

Money better spent! Real-time information about what your engine is doing is invaluable. Bought this sensor because it looked retro and worked fantastic. Easy to connect, easy to set up. The only problem not directly related to the pressure gauge is that it needs to be welded. If you don't weld and don't know any, think twice before you start the installation. Most welding shops I've come across wouldn't weld it because the "job" was too small and not worth their time. Prepare the welding machine before disassembling anything. Otherwise - WOW!
