Review on Delphi GN10434 Plug Ignition Coil by Scott Gamache

Ideal replacement for original Subaru (Diamond) ignition coils. My 2005 WRX has already clocked 162,000 miles and the famous 3rd cylinder ignition coil has started to misfire causing all sorts of handling issues. After scanning the OBD for codes and finding a misfire, I pulled the coil out and switched it to cylinder 1 to narrow down the causes. The next scan revealed a misfire on cylinder 1. At this point I was convinced the problem was in the coil. The Delphi coil fits and works just like the Diamonds and only takes about 10 minutes to change (for an experienced shade tree). The 2 year 36,000 mile warranty is also a plus. If you're wondering whether to buy OE or Delphi, look no further and get Delphi. You will be happy and your wallet will thank you.
