Review on π₯ Enhance Engine Performance with Sierra 18-5438 Ignition Coil by Johnathan Delgado
Arrived DOA/Defect
I always bench test the coil to make sure it meets factory specs. This one didn't even come close. In fact, there was a short in the primary winding, causing the resistance to fluctuate from 12 to 19 ohms when it should be between 0.6 and 0.8 ohms. Sent it back for a refund. The seller immediately provided a prepaid label and a full refund upon receipt. Therefore, always test electronic devices before installation, especially for electronics made in China.
