Review on 🔥 Enhance Ignition Performance with Delphi GN10633 Pencil Coil by Ryan Hoover

Online says Delphi is an OEM supplier. However, I compared the coil to the OEM, it's completely different. The OEM inner core is larger, stronger and well built. The Delphi spool is heavier than the OEM spool, but the inner spool is thinner. Also, I received the 4th coil. different from the other 3 coils. So I brought it back to Revain. I would not recommend this brand. The Spectra coil is better. It has the same structure as OEM. Or you have to spend $10 more on each coil to get an OEM with a Hyundai/Kia logo. In the picture the coil on the left is Delphi, the coil on the right is the original coil.
