October 8, 2018
As a DIY mechanic I find 1AAuto to be a great help with walk-through-the-process videos and quick & professional handling of orders. Recently had the need for just one Ignition Coil/Coil on Plug (COP) for the family car, and along with their good handling of my order--the cost was 50% of what I would have paid locally. I'm fully satisfied with the build quality and performance of the 1AEC100237 Ignition Coil--as I have been with past products. --Dave B.
