Review on 🔥 Enhance Vehicle Performance with Delphi GN10309 Ignition Coil: Reliable and Efficient Spark Ignition Solution by Todd Vesci

Bought 6 of these as 4 of my OEM units on the 3.6 liter DI GM engine failed in my outlook. I knew the originals were OEM Bosch and the GM engine design is questionable, but they were NOT stock and the Delphi units had good reviews. 1 1/2 years later again 3 dropouts. I replaced it with a Bosch and the problem was gone. I will say the units look good and looked like new when I picked them up. No more checking engine codes after replacement.
