Review on Enhanced Performance Motorcraft DG541 Ignition Coil by Allen Hart

They are individually boxed in official Motorcraft bags. Each bobbin case is pre-lubricated and ready to install. Parts have official production marks which cheap Chinese parts do not have. My mechanic warned me not to mess around with a non-OEM on a hybrid for fear of frying the computer. My 2008 Ford Escape Hybrid started misfiring on the way home uphill. Turns out I had dropouts on 1 and 2. This is not uncommon at 108k+. The cover on my small 4 cylinder engine came off immediately (no screws, thanks Ford). Coils and spark plugs were readily available. Some lube on the spark plug threads and dielectric grease on the end of the handle. After starting the car, it became noticeably quieter, the Check Engine light was still on but stopped blinking. After driving a little and restarting the engine, the light went out. Problem solved. It was worth the wait, but you may have to go to Walmart if you're in a hurry and pay an extra $15 for a roll.
