Review on Enhanced Performance DR39T Ignition Coil by Standard Motor Products by Steven Barbon

Made in Taiwan, boxed. 10 minute install for all three and one big difference. The car stumbled and couldn't drive but they happened sporadically, last time was 4 months ago so I replaced them as they broke over time. The big difference in the beginning - almost immediately - is something I forgot as everything fades away. The next thing I noticed was how quickly it accelerated. I replaced the connectors (which were over 100k and the wires before with no significant difference). I'm curious if the gas mileage will increase - seems like a good possibility - this is a 2001 GM car with a 3800 Series II engine. The reason I chose this product was its cost - genuine AC Delco parts (which may have been made on the same factory line as this one, we'll never know) were much more expensive. All AC Delco parts come with a disclaimer that the only real thing is the box the part comes in - the actual part is made by someone - sort of a reference, my Kenmore washing machine is LG, Kenmore dishwasher - jacuzzi etc.
