yibei-tech is a chinese companay, so probably cheap made in china parts. Their ignition coils I saw have a warranty, so I would contact them for a refund. It's one of two ways to push back against the cheap junk coming out of china. The other way is to not buy it in the first place. I overhauled my washing machine in Aug & repaired a gas dryer last week and only installed parts that were Made in USA or Mex. These parts didn't cost more in most cases & not much more otherwise. no cheap chinese junk for me whenever possible.
