    It's hard to beat the OEM ones.

    If you like NGK they make an Iridium plug that worked fine for me.

    I use Brisk silver plugs myself. Once installed on my 2010 GT, the misfires (from oem plugs) as indicated on my digital aeroforce gauges (plugged into OBD port) dropped to zero.

    Yeah, on the brisk train. Expensive...for sure. But the problems they solve speaks volumes. Never had an issue with any of them since I switched. Even when I had one freeze in the plug well I was still able to get it out without damage with an air impact. Really thought I was going to break it with a breaker bar. Lesson learned; a tiny bit of anti-seize on the threads goes a long way preventing any issues getting them out.
