Ngk. The oem is usually the normal way to go for the performance you and your car are used to having. But when you want to kick it up a few notches and treat yourself and your car and at a resonable price there is the NGK NG7862 Manufacturer#7862 NGK Laser Platinum spark plug.
Really there is no one best. A lot of people say that the E3 spark plugs are pretty good but may be a little pricey. I would go with a good name brand like NGK, Bosch, or Denso. Just be sure to correctly gap them.
