Arrived quickly, some defects

Ordered, arrived very quickly. Found that one was defective. I thought the problem was in the wiring harness (there were DTCs for the "x" coil circuit), the wiring harness didn't fix the problem. (Different cylinder than original one caused the misfire). Installed one of the known good original coils, this cylinder went back into the net. I'm nervous that future "new" coil failures will pop up and create dissatisfied customers. The coils that work now can deliver 50kV, take care of the "modular" part of this type of coil.

Pros
  • Improves throttle response and fuel economy, reduces misfires and maintains high performance even after hundreds of miles
Cons
  • Crumpled packaging
